Study of the long-term $BV{R}_c{I}_c$ photometric variability of eight PMS stars in the young open cluster Trumpler 37

Abstract

This paper reports results from our long-term $BV(RI{)}_c$ photometric CCD observations of eight pre-main-sequence stars collected from June 2008 to October 2022. These stars are located in the young open cluster Trumpler 37, in the field of GM Cephei. The observational data indicate that all stars from our study exhibit variability in all-optical passbands, typical for young stars. In this paper, we describe and discuss the photometric behavior of the stars and the possible reasons for their variability. For two of the objects, we identified periodicity in their light variation.
