  • We present the first volume-limited sample of cataclysmic variables (CVs), selected using the accurate parallaxes provided by the second data release (DR2) of the European Space Agency Gaia space mission. The sample is composed of 42 CVs within 150 pc, including two new systems discovered using the Gaia data, and is (77±10) per cent complete. We use this sample to study the intrinsic properties of the Galactic CV population. In particular, the CV space density we derive, ρ=(4.8+0.6−0.8)×10−6pc… CONTINUE READING
