KIC 7732964 – A Possible Candidate FK Com-Type Star

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.
