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.

在这份滚动资助申请中，我们描述了一项太阳系外行星观测和理论研究的跨学科计划，该计划将在埃克塞特大学进行，通过物理学院天体物理学小组与工程、计算和数学学院 (SECaM) 地球物理和天体物理流体动力学中心 (CGAFD) 之间的新合作。该研究计划结合了最先进的观测和理论计算来探测、确定系外行星的特性并对其形成和演化进行建模。我们将对原行星核心的气体吸积形成巨行星进行三维自引力辐射流体动力学模拟，以产生更准确的年轻气体巨行星模型。我们将使用 VLT 和双子座行星成像仪上的自适应光学器件直接对附近年轻恒星周围的气态巨行星进行成像，并使用这些观测结果来测试模型。我们将使用 HST 和斯皮策对凌日行星进行天基观测，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任务 CoRoT 的数据，以检测和表征海王星质量及以下的行星及其所属系统，并搜索巨行星反射的光。
