Scientific paper

Since the early days of X-ray astronomy one of the central questions in our understanding of accretion onto magnetic white dwarfs in compact binaries is whether their observed ratio between soft and hard X-ray emission is in accordance with theoretical expectations or not. We propose to continue our study of this issue with XMM-Newton observations of three soft X-ray selected polars in addition to one system observed during AO-4. The X-ray characteristics of our sample are complementary to the parameter space covered by previous observations of polars with XMM-Newton and Chandra. A detailed study of the spectral omponents, their flux contributions, and the physical structure of the accretion regions in these systems will, therefore, provide new insight into this long-lasting problem.
