Unusual transit observations with PLATO

博士将专注于研究由系外彗星引起的异常凌日特征的特征。这包括使用光度和光谱技术探测和描述系外彗星凌日事件。博士学位将专注于从TESS、CHEOPS、HST和PLATO等太空任务中获取的数据。即将到来的HST观测将使博士生熟悉光谱空间观测。为了准备PLATO的发射并了解该仪器探测外彗星的灵敏度，该学生将进行注入和回收测试。这可能涉及将具有已知参数的系外彗星凌日注入模拟PLATO数据，然后开发检索这些探测结果的方法。一旦它们被检测到，就可以对它们进行建模，以获得吸收深度和大小等信息，然后与注入的物质进行比较。该项目具有灵活性，其确切内容将取决于发现的内容。

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.
