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