  We present a catalog of 150 variable stars, including 13 stars with exoplanet
candidates. 37 stars were identified as variables for the first time. As a
result of a 2.5-year photometric survey of exoplanets, we have obtained and
analyzed light curves for almost 50 thousand stars in fields around white
dwarfs WD 0009+501 and GRW +708247. Here we describe observations and data
processing, the search for variable stars, their cross-identification with
other catalogs and classification. The catalog is published in open access and
contains the primary classification of variability, light curves and their
parameters.
