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.

在这个滚动补助金申请，我们描述了一个跨学科的观测和理论研究计划在太阳系外行星，将在埃克塞特大学进行，通过天体物理组在物理学院和地球物理和天体物理流体动力学中心（CGAFD）在工程，计算和数学（SECaM）的学校之间的新合作。该研究方案结合了最先进的观测和理论计算，以探测、确定太阳系外行星的性质，并对太阳系外行星的形成和演变进行建模。我们将进行三维自引力辐射流体动力学模拟气体吸积的原行星核心，形成巨行星，以产生更准确的年轻气体巨行星模型。我们将使用VLT和Gemini Planet Imager上的自适应光学直接对附近年轻恒星周围的气体巨行星进行成像，并使用这些观测结果来测试模型。我们将利用HST和斯皮策对过境行星进行天基观测，以了解非常接近其恒星的巨行星大气的化学和动力学，并使用对流三维模拟对这些大气进行建模。最后，我们将分析第一个天基凌日行星搜索使命CoRoT的数据，以探测和探测海王星质量及以下的行星及其所属系统，以及搜索巨行星反射的光。
