Abstract	Galactic compact objects with extremely strong ionizedFe emission lines, with the equivalent width (EW) reachingsim 4000 eV, have been discovered with ASCA, includingAX~J1842.8-0423 and RX~J1802.1+1804.These objects are thought to be binary systems containingmagnetized white dwarf (WD). A possible interpretation ofthe strong Fe-K line is the line-photon beaming in the WDaccretion column, due to resonance scattering of line photonsaugmented by the vertical velocity gradient there. To firmlyestablish the proposed mechanism, an XMM observation of a similar system, AX~J2315-592, is proposed. Uninterrupted coverage will accurately quantify how the line equivalent widths of many ion species change as the white dwarf rotates.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
