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.

博士将专注于研究由系外彗星引起的不寻常的过境签名的特征。这包括使用光度和光谱技术探测和表征系外彗星过境事件。博士将专注于从TESS，CHEOPS，HST和PLATO等天基任务中获取的数据。即将到来的HST观测将使博士生熟悉光谱空间观测工作。为了准备PLATO的发射，并了解这种仪器探测外彗星的灵敏度，学生将进行注入和回收测试。这可能涉及将已知参数的系外彗星凌日注入模拟的PLATO数据，然后开发检索这些检测的方法。一旦它们被检测到，它们就可以被建模以获得诸如吸收深度和尺寸等信息，然后与注入的进行比较。该项目具有灵活性，其确切内容将取决于发现的内容。
