Die Entwicklung von Kataklysmischen Variablen und ihr Beitrag zur Galactic ridge- Röntgenemission

01.11.2021 bis 31.10.2024

Cataclysmic variables (CVs) are the most numerous compact binaries in the X-ray sky. Yet their space density and luminosity function, hence their contribution to the total energy output of the Milky Way at high energies is virtually unknown. This situation will be fundamentally changed with eROSITA. Since all types of CVs are X-ray emitters, large volume-limited samples will be constructed for the first time. Based on these we will test current population synthesis models which predict abundant low-luminosity objects. We will quantify the incidence of magnetism on CV evolution.
