This article is a brief survey of our previous work devoted to searching for candidate type FK Com giant stars and an analysis of data for yet another new candidate, KIC 7732964. Establishing that KIC 7732964 belongs to this group of stars requires further study of the evolutionary status of the star (dwarf, subdwarf, or giant). The star has fast rotation and high flare activity, which are more typical of dwarf or subgiant stars. As for other candidates, in the case of KIC 7732964 additional spectral observations are required to establish the absence of binarity, refine the value of the acceleration of gravity, and its spectral classification.

KIC 7732964 – 一个可能的候选 FK Com 型恒星

本文是对我们之前致力于寻找候选型 FK Com 巨星的工作的简要调查,以及对另一个新候选者 KIC 7732964 的数据分析。确定 KIC 7732964 属于这组恒星需要进一步研究演化恒星的状态(矮星、亚矮星或巨星)。这颗恒星自转快,耀斑活动高,这在矮星或亚巨星中更为典型。至于其他候选者,在 KIC 7732964 的情况下,需要额外的光谱观测来确定二元性的缺失、改进重力加速度的值及其光谱分类。
