Abstract

In this study, the distances of stellar systems classiffied as cataclysmic variables in the literature were determined by using the distance compiled from the Bailer-Jones et al. (2021). The spatial distributions of cataclysmic variables in the heliocentric Galactic coordinate system are obtained and their positions in the Hertzsprung-Russell (HR) diagram constructed from Gaia colors are discussed.
