Probing the Composition of Planet-Building Material with ALMA

Department Name: Physics and Astronomy
Abstract
Planetary systems, such as our own, are assembled from the material - dust, gas, and ice - contained in the protoplanetary disk around a newly-born star. Studying the dust and gas orbiting nearby young stars gives us unique insight into how our solar system might have looked prior to the inception of the planets. This enables us to answer some fundamental questions on our origins. Is our solar system unique? Do young planetary systems contain information on the physical and chemical conditions in the natal protoplanetary disk? Are planetary atmospheric compositions set by the molecular content of the planet-forming zone in the disk?
We are in a unique era to begin to address these questions. Not only is the Kepler space observatory (now K2) revealing the extreme diversity of exoplanetary systems, we now have tools at hand to map the physical structure and chemistry across the planet-forming region of nearby protoplanetary disks. The primary tool we use for this is ALMA, the Atacama Large Millimeter/submillimeter Array. ALMA, an interferometer composed of up to 66 antennas, has the sensitivity and spatial resolution to zoom into the planet-forming zone (< 50 au) and reveal the molecular composition of the birth environment of nascent planets. Recent highlights from ALMA include the first detections of so-called complex organic molecules (COMs), molecules consisting of 6 or more atoms which are also thought to be the main feedstock of larger (prebiotic) molecules. COMs also trace the composition of the ice reservoir hosted on cold (<< 100 K) dust grains which are the building blocks of icy planetesimals such as comets. Also revealed via high spatial resolution observations (~0.1"-0.01") are dust gaps and traps, for which one explanation is sculpting by unseen forming planets. What remains to be determined, is the degree to which dust sculpting can influence the chemistry, thus altering composition of planet-building material (both gas and ice) in situ.
This project will investigate the chemistry of organic molecules in nearby planet-forming disks. ALMA observations of gas-phase methanol (CH3OH) of our nearest solar-system analogue, TW Hya, will have the sensitivity and spatial resolution necessary to reveal its distribution and abundance. Of particular interest is whether the methanol emission is coincident with the CO snowline (at 19 au) and/or a planet-carved dust cavity (at 22 au). Analysis of the data using detailed chemical models will reveal its chemical origin and provide vital data for motivating future ALMA searches for even larger (and closer to prebiotic) molecules. In parallel, ALMA observations of known molecular disk tracers, CO, CN, HCN, and HCO+, of the protoplanetary disk encompassing HD 100546, will be used to investigate the effects of planet-carved gaps on the disk chemical structure. HD 100546 is a unique test case because it remains the only known source for which an embedded (proto)planet has been detected in the outer disk (~50 au) and for which existing ALMA data have revealed a dust trap external to the location of the forming planet. The new ALMA data, in combination with detailed chemical models, will reveal whether the forming planet has carved a deep gap in the gas structure at its location, and the molecular emission across the gap will reveal chemical changes induced therein and in the dust traps bordering the planet location. This pilot study, on potential molecular diagnostics of planet-carved gaps, will motivate future ALMA studies of nearby protoplanetary disks which may be host to as yet unseen forming planets.

Planned Impact
The primary impact from this work is via public engagement and outreach with the primary beneficiary being the general public.
ALMA: Revealing Our Origins
**************************************
With its unprecedented sensitivity and spatial resolution at (sub)mm wavelengths, new results from ALMA are of great interest to the general public. One of its primary scientific goals is to reveal the birth environment of planetary systems, which is the first step en route to 'life' and our origins. High-impact results from ALMA are communicated to the general (and international) public via press releases prepared in collaboration with the ALMA observatory (http://www.almaobservatory.org/) and ESO (European Southern Observatory, http://www.eso.org/public/). These are, in turn, picked up by the international press and are promoted nationally and internationally via social media. Leeds astronomers have been involved in several recent press releases regarding high-impact results from ALMA which have also led to engagement with the press via interviews for publication in international and national online media. It is anticipated that the work conducted during this project will lead to similarly high-impact results of international press interest.
Public Engagement at Leeds
**************************************
The Astrophysics Group at Leeds has a strong track record in public engagement and outreach via public talks, participation in initiatives to promote (astro)physics as a career to under-represented demographics, and the organisation of local public events in collaboration with national events such as BBC Stargazing Live. Leeds astronomers have had several high-impact results picked up by the press (in addition to those from ALMA highlighted above). Results from this project will be communicated to the general public during public talks and outreach events.

| Title | From Interstellar Snowflakes to Life |
| Description | This is an exhibition that uses props and audience participation to demonstrate fundamental concepts pertinent to astrophysics, astrochemistry, and astrobiology. It is a collaboration between the grant holder, Dr Catherine Walsh, and an Associate Professor in scenography and performance at the University of Leeds, Dr Joslin McKinney. |
| Type Of Art | Artistic/Creative Exhibition |
| Year Produced | 2017 |
| Impact | This exhibition has been delivered at two public engagement events in 2017 and 2018, and during the course of this grant, is being continually updated, developed, and expanded for future delivery at science festivals and outreach events in 2019. |
| Description | This research involved the imaging and analysis of state-of-the-art data from the Atacama Large Millimeter/submillimeter Array, to answer key questions on the chemical structure and composition of planet- and comet-forming regions around nearby young stars. The findings reported below also laid some of the groundwork for successful follow-up observing programs with ALMA, including the ALMA Large Program, Molecules with ALMA at Planet-forming Scales (MAPS) and also led to the successful award of future funding in the form of a UKRI FLF (PI Walsh: 2021 - 2024) and STFC ERF (PI Ilee: 2022 - 2027). Summarised key findings from these observational studies are: > The first detections of several molecules in protoplanetary disks for the first time, including C34S, 13CS, H2CS, DNC, and C2D (Loomis, ..., Walsh, ... et al. 2020), and 13C17O in the disks of HD163296 and HL Tau (Booth, Walsh, Ilee, et al. 2019; Booth & Ilee 2020). The analysis of 13C17O showed that these disks are more massive that previously thought and also massive enough to form a planetary system. The analysis also suggested that HL Tau is gravitationally unstable. > The successful detection and analysis of key complex organic molecules, CH3CN and CH3OH, in TW Hya (Loomis, ... Walsh, ... et al. 2018) and HD 100546 (Booth, Walsh, et al. 2021), respectively. For HD 100546 we showed, for the first time, that the presence of methanol in this source is a strong indicator of inheritance of ices formed in the molecular cloud from which the star formed. > The first detection of the shock tracer, SO, in the disk around HD 100546 showcasing SO as a potential diagnostic of the presence of otherwise unseen forming planets (Booth, Walsh, et al. 2018). > Deep upper limits on the abundance of H2O and CH3OH in the disk around HD 163296 (Notsu, ..., Walsh, ... et al. 2019; Carney, ..., Walsh, ... et al. 2019), revealing the apparently peculiar chemistry in this source. > We also made the first predictions of dust emission from planet-forming disks with the Square Kilometer Array (SKA) quantifying the resolution and sensitivity needed to resolve planet carved gaps feeding into SKA development and design (Ilee, Hall, Walsh, et al. 2020). |
| Exploitation Route | The outcomes of this funding are mainly of benefit to academic sectors and those involved in telescope design/upgrades and instrumentation development (led by engineering companies in collaboration with astronomers). All data and model results and codes presented in the reported outputs are available to other researchers for use in other investigations and studies and to motivate future observations with ALMA and other telescopes. The detections and analysis presented also feed into laboratory astrophysics in the the development of new laboratory techniques and equipment, that is of use in other areas of physical chemistry (spectroscopy, cold atoms/molecules, condensed phase). |
| Sectors | Other |
| Description | During this award, 22 outreach and public engagement events were designed and delivered, reporting results from this research to the general public via talks and activities at local science festivals and museums (e.g., New Scientist Live), school talks, and talks for special interest groups such as astronomical societies. Further, two press releases were produced in collaboration with ALMA (Atacama Large Millimeter/submillimeter Array) reporting our scientific results to a global audience. And two videos were generated and distributed to the wider public via ESA (European Space Agency). |

| Title | Varied oxygen simulations with WACCM6 (Proterozoic to pre-industrial atmosphere) |
| Description | The history of molecular oxygen (O2) in Earth's atmosphere is still debated; however, geological evidence supports at least two major episodes where O2 increased by an order of magnitude or more: the Great Oxidation Event (GOE) and the Neoproterozoic Oxidation Event. O2 concentrations have likely fluctuated (between 10-3 and 1.5 times the present atmospheric level) since the GOE ~ 2.4 Gyr ago, resulting in a time-varying ozone (O3) layer. Using a three-dimensional (3D) chemistry climate model, we simulate changes in O3 in Earth's atmosphere since the GOE and consider the implications for surface habitability, and glaciation during the Mesoproterozoic. We find lower O3 columns (reduced by up to 4.68 times for a given O2 level) compared to previous work; hence, higher fluxes of biologically harmful UV radiation would have reached the surface. Reduced O3 leads to enhanced tropospheric production of the hydroxyl radical (OH) which then substantially reduces the lifetime of methane (CH4). We show that a CH4 supported greenhouse effect during the Mesoproterozoic is highly unlikely. The reduced O3 columns we simulate have important implications for astrobiological and terrestrial habitability, demonstrating the relevance of 3D chemistry-climate simulations when assessing paleoclimates and the habitability of faraway worlds. |

| PI Contribution | Walsh is the European Co-PI of this large international project team. The team spans four continents (North America, South America, Europe, and Asia) and is made up of > 40 researchers spanning all career stages from MSc level to established group leaders. The Co-PI team, including Walsh, led the submission of the original proposal, and set up the initial collaboration. The Co-PI team, including Walsh, also set the scientific focus and schedule for producing the outputs of the large program. Walsh also led the imaging team of the collaboration which was responsible for generating the pipeline for imaging the data and producing the data products used by the science teams. Walsh and a Leeds-based PDRA, Ilee, also led the science team reporting the results for the large complex organic molecules detected in the sources targeted in the large program. |
| Collaborator Contribution | Other partners in the collaboration led the other 19 outputs of the large program. In addition to the general role of the Co-PI team, one Co-PI, Oberg (CfA, USA), oversaw the management of the collaboration, and another Co-PI, Guzman (Pontificia Universidad Católica de Chile), led the calibration of the raw data. A key CoI, Loomis (NRAO, USA) arranged the computing infrastructure needed to host and image the data. |

| PI Contribution | Walsh is the European Co-PI of this large international project team. The team spans four continents (North America, South America, Europe, and Asia) and is made up of > 40 researchers spanning all career stages from MSc level to established group leaders. The Co-PI team, including Walsh, led the submission of the original proposal, and set up the initial collaboration. The Co-PI team, including Walsh, also set the scientific focus and schedule for producing the outputs of the large program. Walsh also led the imaging team of the collaboration which was responsible for generating the pipeline for imaging the data and producing the data products used by the science teams. Walsh and a Leeds-based PDRA, Ilee, also led the science team reporting the results for the large complex organic molecules detected in the sources targeted in the large program. |
| Collaborator Contribution | Other partners in the collaboration led the other 19 outputs of the large program. In addition to the general role of the Co-PI team, one Co-PI, Oberg (CfA, USA), oversaw the management of the collaboration, and another Co-PI, Guzman (Pontificia Universidad Católica de Chile), led the calibration of the raw data. A key CoI, Loomis (NRAO, USA) arranged the computing infrastructure needed to host and image the data. |

Walsh and a Leeds-based PDRA, Ilee, also led the science team reporting the results for the large complex organic molecules detected in the sources targeted in the large program. |
| Collaborator Contribution | Other partners in the collaboration led the other 19 outputs of the large program. In addition to the general role of the Co-PI team, one Co-PI, Oberg (CfA, USA), oversaw the management of the collaboration, and another Co-PI, Guzman (Pontificia Universidad Católica de Chile), led the calibration of the raw data. A key CoI, Loomis (NRAO, USA) arranged the computing infrastructure needed to host and image the data. |

| PI Contribution | Walsh is the European Co-PI of this large international project team. The team spans four continents (North America, South America, Europe, and Asia) and is made up of > 40 researchers spanning all career stages from MSc level to established group leaders. The Co-PI team, including Walsh, led the submission of the original proposal, and set up the initial collaboration. The Co-PI team, including Walsh, also set the scientific focus and schedule for producing the outputs of the large program. Walsh also led the imaging team of the collaboration which was responsible for generating the pipeline for imaging the data and producing the data products used by the science teams. Walsh and a Leeds-based PDRA, Ilee, also led the science team reporting the results for the large complex organic molecules detected in the sources targeted in the large program. |
| Collaborator Contribution | Other partners in the collaboration led the other 19 outputs of the large program. In addition to the general role of the Co-PI team, one Co-PI, Oberg (CfA, USA), oversaw the management of the collaboration, and another Co-PI, Guzman (Pontificia Universidad Católica de Chile), led the calibration of the raw data. A key CoI, Loomis (NRAO, USA) arranged the computing infrastructure needed to host and image the data. |
