Abstract

We report on a follow-up study of 15 CV candidates, which were discovered by the ROSAT All-Sky Survey and have been identified on the objective prism plates of the Hamburg Quasar Survey so far. For all objects we could obtain low resolution optical spectra confirming 12 CVs. The misidentifications are two quasars and an M-dwarf.

Key words: surveys – X-rays: stars – X-rays: galaxies – stars: novae, cataclysmic variables – stars: binaries: spectroscopic
