|Title||The Quest for a Self-Consistent Model of BF Eri = 1ES 0437-046|

|Description||The X-ray spectrum of BF Eri contains a puzzling contradiction. BF Eri is the optical counterpart of an Einstein slew survey source 1ES0437-046, and was identified as a cataclysmic variable with a massive (>1.23 Msun) white dwarf. As such, we expect a hot, optically-thin, thermal plasma with prominent emission lines of He-like and-or H-like iron. No such lines are seen in the Suzaku observation, showing instead a continuum-dominated spectrum. While this could be due to a low abundance of iron, the equivalent width of the 6.4 keV line suggests a near-solar abundance. Here we propose an XMM-Newton observation of BF Eri to confirm and refine, or refute, these Suzaku results, with the aim of constructing a model for the X-ray emission from BF Eri with a single abundance of iron.|

|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.
