The PhD will be focused on studying the characteristics of unusual transits signatures caused by exocomets. This includes the detection and characterisation of exocometary transit events using both photometric and spectroscopic techniques. The PhD will focus on data taken from space based missions such as TESS, CHEOPS, HST and PLATO. Upcoming HST observations will give the PhD student familiarity with working with spectroscopic space based observations. To prepare for the launch of PLATO and to understand the sensitivity of this instruments to detecting exocomets, the student will be performing injection and retrieval tests. This will likely involve injecting exocometary transits with known parameters into simulated PLATO data and then develop methods to retrieve these detections. Once they have been detected they could be modeled to get information such as absorption depth and come size and then compared to what was injected. There is flexibility in the project, and it's exact content will depend on what discoveries are made.

博士将集中于研究由外虫组引起的异常转运特征的特征。这包括使用光度法和光谱技术对外量学转运事件的检测和表征。博士将重点关注从苔丝，Cheops，HST和Plato等空间任务中获取的数据。即将进行的HST观察将使博士生熟悉基于光谱空间的观察。为了准备柏拉图的推出，并了解该工具对检测Exocomets的敏感性，学生将进行注射和检索测试。这很可能涉及将已知参数的外量学转移注入模拟的柏拉图数据，然后开发用于检测这些检测的方法。一旦检测到它们，就可以对它们进行建模以获取吸收深度和大小等信息，然后将其与注射的信息进行比较。该项目具有灵活性，其确切的内容将取决于发现了哪些发现。
