摘要:

我们定义了可能出现在TESS输入目录(TIC)中的各种类型的“幻影”恒星,并提供了目前已知情况的例子和列表。我们提出了一种方法,可用于检查幻影周围的任何感兴趣的对象在TIC,我们提出了一种方法,相应地纠正TIC报告的通量污染因子。我们检查了截至2020年7月21日已知的所有2077个TESS感兴趣对象(TOI)(扇区1至24),并将291颗恒星的更正发送到MAST,将其整合到公开可用的TIC-8中,将其更新为TIC 8.1。我们利用所获得的经验构建了一个搜索“幻影”的全天空算法,该算法将3400万次更新集成到TIC 8.2中。

英文摘要:

We define various types of "phantom" stars that may appear in the TESS Input Catalog (TIC), and provide examples and lists of currently known cases. We present a methodology that can be used to check for phantoms around any object of interest in the TIC, and we present an approach for correcting the TIC-reported flux contamination factors accordingly. We checked all 2077 TESS Objects of Interest (TOIs) known as of July 21st 2020 (Sectors 1 to 24) and sent corrections for 291 stars to MAST where they are integrated into the publicly available TIC-8, updating it to TIC 8.1. We used the experience gained to construct an all-sky algorithm searching for "phantoms" which led to 34 million updates integrated into TIC 8.2.
