在第二个供资期间，研究股继续致力于通过涉及实验、理论和建模活动的跨学科方法，提高对行星内部的组成和结构的了解。我们将研究造岩矿物和复杂分子混合物的物理性质，它们与迄今发现的最丰富的太阳系外行星有关：超级地球和海王星大小的行星。我们将使用新的高压物理方法对结构特性和相稳定性进行实验研究，这些方法使我们能够获得与深部行星内部相关的压力-温度区域。同时，将进行从头计算模拟，以预测这些材料在广泛的压力和温度范围内的热物理性质。这些模拟将以实验为基准，但对于拟议实验的准备和评估也将是重要的。获得的数据将被用来约束新的内部和内部模型，以及超级地球和类海王星行星的演化，并用于评估它们的潮汐响应，其特征是Lovennbers。这些结果将用于评估来自开普勒、盖亚、苔丝、契奥普斯和柏拉图2.0等太空任务的太阳系外行星的观测数据，并将对它们的形成、演化和内部结构产生新的见解。

In the second funding period, the Research Unit continues to aim at improving the understanding of the composition and structure ofplanetary interiors through an interdisciplinary approach, involving experiments, theory, and modeling activities. We will study thephysical properties of rock-forming minerals and complex molecular mixtures, which are relevant for the most abundant extrasolar planetsdetected so far: super-Earths and Neptune-sized planets. Structural properties and phase stabilities will be investigated experimentallyusing novel methods of high pressure physics that enable us to access the pressure-temperature regime relevant for deep planetaryinteriors. Simultaneously, ab initio simulations will be performed in order to predict the thermophysical properties of these materials for awide range of pressure and temperature. These simulations will be benchmarked by experiments, but will also be important for thepreparation and evaluation of the proposed experiments. The acquired data will be used to constrain new models for the interior andthe evolution of super-Earths and Neptune-like planets and for the evaluation of their tidal response, which is characterized by Lovenumbers. The results will be applied to evaluate observational data for extrasolar planets from space missions such as Kepler, Gaia, TESS,CHEOPS, and PLATO 2.0 and will produce new insight in their formation, evolution, and interior structure.
