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.

该博士学位将专注于研究系外彗星引起的不寻常凌日特征的特征。这包括使用光度和光谱技术来检测和表征彗星外凌日事件。该博士将重点研究从 TESS、CHEOPS、HST 和 PLATO 等太空任务获取的数据。即将进行的 HST 观测将使博士生熟悉基于光谱空间的观测。为了准备 PLATO 的发射并了解该仪器检测系外彗星的灵敏度，学生将进行注入和回收测试。这可能涉及将已知参数的外彗星凌日注入模拟柏拉图数据中，然后开发方法来检索这些检测结果。一旦检测到它们，就可以对其进行建模，以获得吸收深度和尺寸等信息，然后与注入的内容进行比较。该项目具有灵活性，其具体内容将取决于取得的发现。
