Could cataclysmic variables be sources of gravitational waves?

The detection of gravitational waves has started the field of multi-messenger gravitational wave astronomy. Cataclysmic variables are binary systems that are candidates for gravitational wave emission in the frequency band of space based interferometer LISA, scheduled for launch in 2034. This paper presents an estimation of the gravitational emission for a sample of more than one thousand cataclysmic variables using the distances estimated by the Gaia observatory. It will be shown that the strongest emission is expected from short period cataclysmic variables belonging to the WZ Sge and AM CVn families.
