Title Characterization of hard X-ray selected CV binaries


DOI 10.5270/esa-rdhvbp8
Author Dr Domitilla de Martino
Description About 20% of hard X-ray galactic sources detected in the INTEGRAL and Swift surveys are accreting white dwarf binaries (CVs). The majority harbours asynchronously rotating magnetic primaries, which are disputed to be the dominant galactic population of low-luminosity X-ray sources. Optical follow-ups provide good candidates but a secure identification resides in the X-rays. With XMM-Newton we could successfully prove or disprove the magnetic nature for 26 sources. We here propose to continue our identification programme with 10 new candidates with the ultimate goal to obtain a true census of the first volume-limited sample of hard X-ray CVs, in view of the accurate distances to be provided by Gaia.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
