Using peak-bagging to constrain the distribution of near-surface magnetic activity of solar-like oscillators.

Abstract
Summary: This project looks at the application of asteroseismology to studying the near-surface magnetic activity of stars. We know that the Sun has activity which manifests in bands of constant latitude and this work studies how we can use solar-like oscillations to constrain the distribution of activity on other stars. This involves developing methods of "peak-bagging" stellar oscillation spectra by fitting complex parametric models to the data.

| Results and Impact | I helped organise a conference day open to all postgraduate research students at the University of Birmingham. Speakers were from external companies and given by postgraduates. I also gave a talk on my current work and I was approached by the BLUEBear HPC team and asked to help beta test their system since my work would be a good test. I also had many questions from the industry visitors about my techniques. |

| Results and Impact | This annual conference saw around 150 researchers attend from the stellar astrophysics community. I gave a 12 minute talk with 5 minutes of questions on the paper I had recently published. I had numerous questions from researchers and several continued discussions afterwards with potential for further related work. |
