In this Rolling Grant application, we describe an interdisciplinary programme of observational and theoretical research in extrasolar planets, to be conducted at the University of Exeter, through a new collaboration between the Astrophysics Group in the School of Physics and the Centre for Geophysical and Astrophysical Fluid Dynamics (CGAFD) in the School of Engineering, Computing and Mathematics (SECaM). The research programme combines state-of-the-art observations and theoretical calculations to detect, determine the properties of, and model the formation and evolution of extrasolar planets. We will perform three-dimensional self-gravitating radiation hydrodynamical simulations of gas accretion by a protoplanet core to form giant planets to produce more accurate models of young gas giant planets. We will directly image gas giant planets around young nearby stars using adaptive optics on the VLT and the Gemini Planet Imager and use these observations to test the models. We will undertake space-based observations of transiting planets using HST and Spitzer to understand the chemistry and dynamics of the atmospheres of giant planets that are very close to their stars and model these atmospheres using convective three-dimensional simulations. Finally, we will analyse the data from CoRoT, the first space-based transiting planet search mission, to detect and characterise planets of Neptune-mass and below and the systems they are part of, as well as search for light reflected by giant planets.

在此滚动赠款应用程序中，我们通过在埃克塞特大学进行了一项跨学科的观察和理论研究计划，该计划将在埃克塞特大学进行，这是通过物理学的天体物理学组与地球物理和天体物理学和天文学流体动力学中心（CGAFD）的新合作（CGAFD）在工程学和数学学院（计算和数学）（CGAFD）（CGAFD）的。研究计划结合了最新的观察结果和理论计算，以检测，确定和建模外星外行星的形成和演变。我们将对原球星芯对气体积聚的三维自我辐射辐射模拟模拟，以形成巨型行星，以生成更准确的年轻气体巨型行星模型。我们将使用VLT和Gemini Planet Imager上的自适应光学器件直接对附近恒星周围的气体巨型行星进行成像，并使用这些观测值来测试模型。我们将使用HST和Spitzer对过境行星进行基于空间的观测，以了解巨型行星的化学和动力学，它们非常接近其恒星，并使用对流的三维模拟对这些大气进行建模。最后，我们将分析Corot的数据，Corot是第一个基于空间的透明行星搜索任务，以检测和表征Neptune-Mass及以下的行星以及它们所属的系统，以及搜索巨型行星所反映的光。
