Physical properties of AM CVn stars: New insights from Gaia DR2

by G. Ramsay, M. Green, T. R. Marsh, et al. A&A 620, A141


AM CVn stars are important gravitational wave sources. The authors have determined absolute magnitudes and mass-transfer rates of AM CVn stars as function of orbital periods, which are crucial to our understanding of evolutionary channels and their space density.
