论文摘要
我们报告了基于感兴趣的苔丝对象，在开放群集和年轻的恒星协会中搜索候选行星候选者的结果。我们在第二个Gaia数据发布中发现了一个确认的星球，一个有前途的候选人，一个棕色矮人和三个未经验证的行星候选者。我们根据其基本参数，会员概率和Exofop-Tess网站的观察说明讨论单个行星明星系统。我们还通过使用Banyan $σ$ Bayesian算法找到了年轻的恒星协会的十个候选人（$> $ 95％）。在十个候选人中，有五个是已知的行星系统。我们使用苔丝光曲线估算宿主恒星的旋转周期，并根据陀螺仪估算其年龄。有两个具有定期差异的候选人可能是年轻的行星，但他们对年轻恒星协会的确切成员资格仍然未知。
We report the results of our search of planet candidates in Open Clusters and Young Stellar Associations based on the TESS Objects of Interest Catalog. We find one confirmed planet, one promising candidate, one brown dwarf, and three unverified planet candidates in a sample of 1229 Open Clusters from the second Gaia data release. We discuss individual planet-star systems based on their basic parameters, membership probability, and the observation notes from the ExoFOP-TESS website. We also find ten planet candidates (P $>$ 95%) in Young Stellar Associations by using the BANYAN $Σ$ Bayesian Algorithm. Among the ten candidates, five are known planet systems. We estimate the rotation periods of the host stars using the TESS light curves and estimate their ages based on gyrochronology. Two candidates with periodic variations are likely to be young planets, but their exact memberships to Young Stellar Associations remain unknown.
