Magnetic accretion in high-accretion rate polars
Abstract
The spectral components of polars were barely disentangled by previous X-ray missions. The physics of magnetic accretion non-relativistic environment is therefore still puzzling. XMM-Newton can solve the riddle, but the frequent low states prevented systematic studies of high-accretion rate polars (HARPs). We thus began TOO-like XMM-Newton observations of the brightest systems in their heigh states. We are in the process creating a synoptic view on the HARPs and propose to continue in AO8 with one further trigger. We investigate the hard X-ray emitting shock, the heated accretion pole cap, the atmosphere of the white dwarf, absorption in the shock and in the flow, the lines in the flow and the reflection from the white dwarf by phase-resolved CCD- and RGS-spectroscopy and high-speed OM-photometry.
