This project will make use of novel data from the NASA Transiting Exoplanet Survey Satellite (TESS). TESS is the first space mission to provide nearly all-sky photometry, covering an area 400 times larger than that of the previous NASA planet finding-mission, called Kepler (Borucki et al. 2010). During this PhD project we will use these state-of-the-art observations to understand not only exoplanets, but also their host stars. The latter will consist of an investigation of stellar oscillations, a technique known as asteroseismology. Employing asteroseismology, we will seek to gain a detailed insight into the properties of exoplanet host stars, and link these findings to the properties of their exoplanets. In this way, we will curate a gold sample of exoplanet systems that are known in exquisite detail, and use this sample to learn about the formation of exoplanet systems as well as our own solar system.

该项目将利用美国航天局凌日系外行星勘测卫星（TESS）的新数据。TESS是第一个提供几乎全天空测光的太空使命，覆盖的区域是之前NASA行星发现使命开普勒（Borucki et al. 2010）的400倍。在这个博士项目中，我们将使用这些最先进的观测方法来了解系外行星，以及它们的宿主恒星。后者将包括对恒星振荡的调查，这是一种称为星震学的技术。利用星震学，我们将寻求详细了解系外行星宿主恒星的特性，并将这些发现与其系外行星的特性联系起来。通过这种方式，我们将精心策划一个已知的系外行星系统的黄金样本，并使用这个样本来了解系外行星系统以及我们自己的太阳系的形成。
