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.

概要：该项目着眼于应用星震学研究恒星近地表的磁活动。我们知道，太阳的活动表现在纬度不变的波段，这项工作研究了我们如何利用类似太阳的振荡来限制其他恒星上活动的分布。这涉及到通过将复杂的参数模型拟合到数据中来开发“峰值装袋”恒星振荡光谱的方法。
