Contribution

It offers a new analysis of the galactic distribution and HR diagram placement of cataclysmic variables based on Gaia data and updated distance measurements.

Findings

Distribution of CVs in the Galaxy mapped

Positions of CVs in the HR diagram discussed

Distances refined using Gaia data

Abstract

In this study, the distances of stellar systems classified as cataclysmic variables in the literature were determined by using the distance compiled from 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.
