Characterization of hard X-ray selected binaries: a census of magnetic CVs
Abstract
The INTEGRAL and SWIFT satellites detected a large number of galactic X-ray sources above 20keV,among which ~6-7% identified as accreting white dwarf binaries. Among known systems most harbour asynchronously rotating magnetic primaries, suggesting that this formerly small subclass could be an important contributor to the galactic X-ray binary populations. However, most newly discovered sources are proposed as magnetic cataclysmic variables through optical spectra. XMM-Newton demonstrated unique potential to infer their true nature through the detection of X-ray pulses and study of broad-band spectra. We propose 6 new sources that, if all confirmed as magnetics, will increase by 35% the hard X-ray sample enabling a true census of the first volume-limited sample
