Two new variables in the central region ofthe globular cluster M 5.
Abstract
The discovery of two variable stars in the central region (r is less than about 2 arcsec) of the globular cluster M5 is reported. Their coordinates, periods, and amplitudes of brightness variability are determined. The obtained light curves and periods of these stars are typical of RR Lyrae variables (RRc).
