Description We propose to observe the peculiar neutron star low mass X-ray binary (NS-LMXB) 2S 1803-245 in quiescence. Together with EXO 1745-248, it is the only transient that reached peak luminosities comparable to the Eddington- limit. This makes 2S 1803-245 one of the thermally brightest NSs in quiescence according to the cooling theory, and therefore one of the best quiescent NSs to investigate. Furthermore, EXO 1745-248 showed enhanced cooling and its quiescent spectrum was completely dominated by a power-law tail, suggested to be related to a high magnetic field strength NS (as is also suggested in the brightest NS-LMXBs). This makes 2S 1803-245 an excellent candidate to verify the connection between high magnetic field strength NS and the high peak luminosity during outburst.

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.
