The DFG Research Unit "Blue Planets around Red Stars" exploits scientific data from one of the largest radial velocity (RV) surveys for planets around nearby, cool dwarf stars. Together with five Spanish partner institutes and the Observatory Calar Alto in Andalucia, the Research Unit members built two specialized spectrographs CARMENES that are in operation since Jan 1, 2016. The consortium receives 750 (useful) observing nights as Guaranteed Time Observations (GTO), which are used for the search for low-mass planets around cool stars. During the first funding period, the Research Unit enabled us to fully exploit the scientific data from our survey. The results from the first period include the discovery of 19 planets, among them highlights like a long-period planet around Barnard's star (the second closest star system to Earth), a two-planet system around Teegarden's star (an ultra-cool dwarf only 12 light years away), and a giant planet in orbit around a low-mass star (the existence of GJ 3512b requires non-standard modes of planet formation). Furthermore, in-depth characterization of the stars, of RV methods at long wavelengths, and the analysis of planetary atmospheres are among the key results of the Research Unit. In this renewal proposal, we are asking for the second phase of our Research Unit during which we want to continue the successful work on CARMENES data. For the second phase, we concentrate on the planets and their atmospheres, and we aim to include the analysis of transiting planets discovered by the TESS satellite.

DFG研究单位“红星周围的蓝色行星”利用了最大的径向速度（RV）调查之一的科学数据，这些调查是对附近冷矮星周围的行星进行的。研究小组成员与五个西班牙合作机构和安达卢西亚的Calar Alto天文台一起，建造了两台专业光谱仪CARMENES，自2016年1月1日起投入使用。该联盟接收750个（有用的）观测夜作为保证时间观测（GTO），用于寻找围绕低温恒星的低质量行星。在第一个资助期内，研究小组使我们能够充分利用我们调查的科学数据。第一个周期的结果包括发现了19颗行星，其中最引人注目的是巴纳德恒星（距离地球第二近的恒星系统）周围的长周期行星，蒂加登恒星周围的双行星系统（距离地球只有12光年的超冷矮星），以及一颗围绕低质量恒星运行的巨大行星（GJ 3512b的存在需要非标准的行星形成模式）。此外，对恒星的深入描述、对RV长波方法的研究以及对行星大气的分析都是该研究单位的主要成果。在这份更新提案中，我们要求我们的研究部门进入第二阶段，在此期间，我们希望继续成功地研究CARMENES数据。在第二阶段，我们将集中研究行星及其大气层，我们的目标是包括对TESS卫星发现的凌日行星的分析。
