- Аннотация: The light curves for almost 50 thousand stars with magnitudes m∈[11.m5,19.m5] have been obtained over 2.5 years at SAO RAS in the process of conducting an exoplanet survey in roughly 1.∘5-sized fields around the white dwarfs WD 0009+501 and GRW +708247. In this paper we present a catalog of variable stars that have been found in the considered regions. Periodogram analysis was used as the main variation search method. The catalog includes 150 periodic variable stars: 113 of them have been known previously, and for the remaining 37 variations have been discovered for the first time. These stars were classified according to the nature of the variations into four eclipsing variable and three pulsating types, as well as rotating stars. We present the periods and variation amplitudes in the range of P∈[0.d036,32.d14] and Δm∈[0.m0064,1.m45], determined from the investigated data.
