The cold, the hot, and the puffy. Atmospheric lessons from three transiting exoplanets

系外行星可以在凌日和日食事件中被探测和研究，从地球上看，当行星从前面经过或被其恒星遮盖时。这些事件提供了有关系外行星大气的关键信息，可用于测量行星的温度、大气成分、热结构和探测云或阴霾。在Sing博士的带领下，哈勃太空望远镜和10.4米GTC上的两个大型项目正在进行中，他们对热的木星系外行星进行了大规模的大气光谱调查。木星系外行星是被发现的靠近其母恒星的气态巨行星。在这个项目中，这些数据集将与斯皮策数据一起进行分析，建模，并用于建立完整的光学到红外传输光谱。我们的观测工作将与广泛和包容的理论建模计划相结合，在该计划中，我们将把各种关键的物理效应结合在一起，特别是云和阴霾，用3D全球环流模式以自洽的方式模拟整个大气。重点将放在两个关键的科学贡献上，解决为什么一些热木星有阴霾，而另一些没有，以及平流层的存在或不存在的悬而未决的问题。

Exoplanets can be detected and studied in transit and eclipse events, when a planet passes in front or is eclipsed by its star as viewed from the Earth. These events provide key information about the atmosphere of exoplanets, and can be used to measure a planets temperature, atmospheric composition, thermal structure, and detect clouds or hazes. Two large programmes on the Hubble Space Telescope and 10.4 meter GTC have been underway lead by Dr. Sing performing a wide-scale atmospheric spectral survey of hot Jupiter exoplanets, gas giant planets found close to their parent stars. For this project, these datasets will be analysed along with Spitzer data, modelled, and used to build complete optical to infrared transmission spectra. Our observational efforts will be combined with a broad and inclusive theoretical modeling programme, where we will incorporate a full range of crucial physical effects together, including notably clouds and hazes, modelling the complete atmosphere in a self-consistent manner with a 3D global circulation model. Focus will be given on on two key scientific contributions, addressing why some hot Jupiters have hazes & clouds while others do not, and the outstanding issue on the presence or absence of stratospheres.
