Magnetic accretion in high-accretion rate polars
Abstract
The spectral components of polars strongly magnetic CVs were barely disentangled by previous X-ray missions. The physics of accretion in a strongly magnetic, non-relativistic environment is therefore still puzzling. XMM-Newton can solve the riddle, but the frequent low states of the brightest members prevented systematic studies. We thus began TOO-like XMM-Newton observations of the brightest systems in their high states. We are in the process creating a synoptic view on the HARPs and propose to continue in AO12 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.
