达尔文的目标恒星目录：搜索类地行星的附近恒星样本
Target star catalog for Darwin: Nearby Stellar sample for a search for terrestrial planets
摘要：
为了评估和发展搜索类地系外行星的任务概念，我们准备了一份潜在目标系统的清单。在本文中，我们提出和讨论的标准，选择潜在的目标恒星适合于搜索类地行星，特别强调的方面，这些恒星系统的宜居带。在这些区域内发现的行星可能能够承载复杂的生命形式。我们得出一个最终的目标星样本的潜在目标星，达尔文全天星表（DASSC）。DASSC包含2303个已识别的天体，其中284颗是F型，464颗G型，883颗K型，615颗M型星，57颗没有B-V指数的星。其中949个天体在DASSC中被标记为多系统，导致1229颗单主序星，其中107颗是F型，235颗是G型，536颗是K型，351颗是M型。我们从DASSC的两个技术设计，初始的基线设计和先进的艾玛设计以及目录使用的内部工作角切断配置相关的子目录。讨论了不同类型恒星的选择准则、导出参数和样本的完备性。
英文摘要：
In order to evaluate and develop mission concepts for a search for Terrestrial Exoplanets, we have prepared a list of potential target systems. In this paper we present and discuss the criteria for selecting potential target stars suitable for the search for Earth like planets, with a special emphasis on the aspects of the habitable zone for these stellar systems. Planets found within these zones would be potentially able to host complex life forms. We derive a final target star sample of potential target stars, the Darwin All Sky Star Catalog (DASSC). The DASSC contains a sample of 2303 identified objects of which 284 are F, 464 G, 883 K, 615 M type stars and 57 stars without B-V index. Of these objects 949 objects are flagged in the DASSC as multiple systems, resulting in 1229 single main sequence stars of which 107 are F, 235 are G, 536 are K, and 351 are M type. We derive configuration dependent subcatalogs from the DASSC for two technical designs, the initial baseline design and the advanced Emma design as well as a catalog using an inner working angle cut off. We discuss the selection criteria, derived parameters and completeness of sample for different classes of stars.
