Complex magnetic fields: an enigma of solar plasmas (Dundee-Durham consortium)
Lead Research Organisation:
Durham University
Department Name: Mathematical Sciences
Abstract
The outer atmosphere of the Sun, the solar corona, is a dynamic plasma permeated by a magnetic field. This magnetic field is responsible for creating long-lived structures such as coronal loops, for heating the corona to its multi-million degree temperatures, and for explosive events such as solar flares and coronal mass ejections. These powerful explosions can greatly influence the Earth and its surrounding environment. They create the Northern and Southern lights, but also have the potential to damage satellites, power grids and pipelines, disrupt communications systems, and endanger astronauts. Understanding how these explosive processes take place requires a detailed understanding of the behaviour of the Sun's magnetic field, which is characterised by its complex three-dimensional structure. Gaining such an understanding is the aim of this work programme and is part of a wider goal in the scientific community of understanding the formation of structures in astrophysical plasmas.
Recent observational advances are providing us with a more and more detailed view of the Sun's magnetic field. But each increase in spatial resolution reveals finer scale magnetic structures, down to the resolution limit of even the most advanced telescopes. What is more, each increase in time cadence reveals more complex dynamics that shape the magnetic field and plasma on all scales. The over-arching theme of this consortium proposal is to explore the physical consequences of this magnetic complexity. We aim to understand how such complex magnetic fields are formed, how they evolve, and how they can build up and explosively release extreme amounts of energy. These questions are challenging, but must be addressed if we are to understand the full implications of what we are now observing.
We will address problems such as: What is the mechanism that makes the solar corona so hot? How do explosive events occur in the Sun's atmosphere? Can we develop new tools to help analyse these complex magnetic fields, and can we apply these tools to the evolution of the corona on global scales? What controls the lowest energy state to which the magnetic field of the corona can relax, and therefore how much energy is available to heat the plasma? How are particles accelerated in particular complex magnetic field structures?
We will use a combination of numerical simulations and mathematical modelling to tackle these questions, primarily using the non-linear partial differential equations of magnetohydrodynamics. The modelling will take input from the latest generation of solar telescopes, using various observations to verify and refine the theory. Combined, the results should help not only to explain and predict events in the solar corona and help answer STFC's Science Roadmap Challenge B:2 ("How does the Sun influence the environment of the Earth and the rest of the Solar System?") but also to understand some of the basic plasma physical processes that go on throughout the Universe.

Planned Impact
Eruptive magnetic storms on the Sun (Coronal Mass Ejections) regularly reach the Earth's space environment. The economic consequences of this space weather can be severe, and include damage to satellites and power grids, corrosion of oil and gas pipelines and disruption of communication systems. Furthermore, these events may endanger the health of astronauts and those onboard high-flying aircraft. The proposed research seeks to develop an understanding of how complex magnetic structures in the Sun's atmosphere change and interact, with these interactions being a critical part of the chain of events that generates solar eruptions. As such, a possible major impact of the proposed research will be on the international effort to develop reliable space-weather forecasting systems (given notice, defensive measures can the taken against the aforementioned effects).
Project 1.2, examining the consequences of complex magnetic fields in the global solar corona, will allow for significantly improved simulations of the Sun's magnetic field on global scales. A potential impact here will be on reconstructions of the Sun's magnetic field in the past which, in turn, will affect reconstructions of the Earth's climate in the past.
The proposed research should be seen in the wider framework of the analysis of complex multi-scale systems which we encounter in many areas of science: the weather, cellular networks, material sciences, neurosciences, nuclear sciences, etc. The theoretical tools and method created for investigating astrophysical plasmas have both benefited from and contributed to progress in these areas via exchanges of ideas, software and human resources.
More generally, astronomy has a strong cultural impact. Due to the Sun's close proximity and the stunning images being gathered by new satellites, solar physics has a great capacity to get young people interested in science, contributing to UK's skilled labour market. We will engage with schools and the general public on our research findings through the Schools Outreach Programme of the Division of Mathematics in Dundee, via press releases, articles in popular science magazines and public events such as the Dundee Science Festival. These methods are further documented in the Outreach section of the Pathways to Impact document.

OBSERVATIONS OF A HYBRID DOUBLE-STREAMER/PSEUDOSTREAMER IN THE SOLAR CORONA
in The Astrophysical Journal
Description | Progress has been made on all projects. Here is a summary of some of our key findings: (1) We have shown that the field-line helicity is a robust and useful analytical tool for understanding the dynamics of plasmas with complex magnetic fields. In particular, we have demonstrated how it evolves during a turbulent plasma relaxation. Our analysis has unequivocally demonstrated the importance of higher topological invariants in constraining the evolution, and moreover has suggested how we could in future make predictions of the end state of such relaxation events. This work has implications for understanding heating in the Sun's atmosphere, but also more generally for understanding plasma relaxation events elsewhere in astrophysics or in laboratory plasmas (e.g. fusion machines). (2) We have developed an improved "flux transport" model for the evolution of magnetic fields on the Sun's surface. The improvement is to account better for the structure of solar active regions, leading to better predictions of the overall magnetic field at the end of the solar cycle. This work has implications for understanding both short and long-term solar activity. (3) We have studied the influence of our "non-potential" model for reconstructing the Sun's coronal magnetic field on predictions of the solar wind. Importantly, we have shown that there is a significant change compared to the standard "potential" model used in current space weather predictions. We are working with both the UK Met Office and US Air Force to further assess the possible benefits of our model for prediction. |
Exploitation Route | Our tools for analysing plasma relaxation can be applied to a wide variety of systems in astrophysics, laboratory plasma physics or even more widely in fluids. Our work on improvements to space weather prediction has potential impact for predictions made by NOAA in the US and by the UK Met Office. |
