Description We propose to observe any Be X-ray transient after its next type-II outburst during a potential quasi-stable low-luminosity plateau phase that has been identified in several sources. The origin of this plateau phase is still unclear and could be due to the cooling of an accretion heated neutron star crust or due to residual accretion onto the neutron star surface at very low rates. Crustal cooling has been well- studied in low magnetic field neutron stars where the magnetic field does not play a r^ant role, but not much is known about how much this process could be affected by the high magnetic fields found of the neutron stars in Be X-ray transients. Our proposed observation will be the second one done in this enigmatic plateau state using high quality spectral and timing data.

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.
