Title The energy budget of soft X-ray selected polars (continued)


DOI 10.5270/esa-x9ekmmq
Author Dr Klaus Reinsch
Description 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.

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.
