Spot Activity of Stars in The Uma Moving Group

The spot activity of stars in the UMa moving group was investigated based on the TESS Archive. The values of rotating period and spot parameter S (a fraction of the visible star surface filled with spots) of 56 stars in the moving group were estimated. The obtained results were compared with the results on the Beehive cluster.

Abstract

The spot activity of stars in the UMa moving group was investigated based on the TESS Archive. The values of rotating period and spot parameter S (a fraction of the visible star surface filled with spots) of 56 stars in the moving group were estimated. The obtained results were compared with the results on the Beehive cluster.
