Unusual transit observations with PLATO

博士将专注于研究由系外彗星引起的不寻常凌日信号的特征。这包括利用光度学和光谱学技术探测和描述地外凌日事件。博士将专注于从TESS、CHOPS、HST和柏拉图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基于光谱空间的观测工作。为了为柏拉图的发射做准备，并了解该仪器对探测外彗星的敏感性，学生将进行注入和回收测试。这很可能涉及将已知参数的行星际凌日注入到模拟的柏拉图数据中，然后开发方法来恢复这些探测。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，然后与注射的信息进行比较。这个项目有灵活性，它的确切内容将取决于有什么发现。

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.
