Title Magnetic accretion in high-accretion rate polars

Author European Space Agency
Description The spectral components of polars -- strongly magnetic CVs -- are barely
disentangled without sufficient spectral coverage. XMM-Newton plus NuSTAR can
solve the riddle but the frequent low states of the brightest members prevented
systematic studies of high-accretion rate polars (HARPs). We thus began TOO-like
XMM-Newton observations of the brightest systems in their high states and
propose to continue in AO13 with one further trigger. We will investigate the
physics of the hard X-ray emitting shock, the heated accretion pole cap, the
atmosphere of the white dwarf, the absorption in the shock and in the flow, the
lines in the accretion flow and the reflection from the white dwarf by
phase-resolved X-ray spectroscopy and high-speed OM-photometry.

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.
