CM Del

An Eclipsing Cataclysmic Variable Star

CM Del is a cataclysmic variable star located in the constellation Delphinus. It is classified as a nova-like variable and is likely an eclipsing system composed of a white dwarf and a donor star. Mass transfer from the donor occurs via an accretion disk around the white dwarf. CM Del exhibits brightness variations typical of unstable accretion behavior, but it remains relatively poorly studied compared to other cataclysmic variables in the literature.
