论文摘要
报告了新调查的第一个结果，该结果探讨了ESA-GAIA任务的第二个数据发布，以搜索（社区）感兴趣的对象的出色伴侣并表征其属性。总共提出了193个二进制和15个分层三星级系统，在1391个目标恒星中检测到，它们位于太阳周围的距离距离大于500pc的距离。同伴和目标是等距的，并具有共同的适当运动，正如重力结合的恒星系统所期望的那样，其精确的GAIA星形统计证明了这一点。同伴在约0.08 $ m_ \ odot $和3 $ m_ \ odot $之间展示质量，并且最常在0.13至0.6 $ m _ {\ odot} $之间找到。同伴与目标分开约40到9900AU，而他们的频率随着分离的增加而不断降低。虽然大多数检测的同伴是较晚至中间矮人的晚期，但在这项调查中也发现了5个白矮人的同伴，其真实本质是通过其光度特性揭示的。
The first results of a new survey are reported, which explores the 2nd data release of the ESA-Gaia mission, in order to search for stellar companions of (Community) TESS Objects of Interest and to characterize their properties. In total, 193 binary and 15 hierarchical triple star systems are presented, detected among 1391 target stars, which are located at distances closer than about 500pc around the Sun. The companions and the targets are equidistant and share a common proper motion, as it is expected for gravitationally bound stellar systems, proven with their accurate Gaia astrometry. The companions exhibit masses in the range between about 0.08$M_\odot$ and 3$M_\odot$ and are most frequently found in the mass range between 0.13 and 0.6$M_{\odot}$. The companions are separated from the targets by about 40 up to 9900au, and their frequency continually decreases with increasing separation. While most of the detected companions are late K to mid M dwarfs, also 5 white dwarf companions were identified in this survey, whose true nature is revealed by their photometric properties.
