Description We propose a 35 ks XMM-Newton observation during the outburst of a very-faint
X-ray transient. These peculiar X-ray binaries are underluminous by orders of
magnitudes compared to the well-studied classical (bright) X-ray transient
population. Some of them have been identify as accreting neutron stars, whereas
only one black hole has been conclusively identified so far. However, the nature
of the vast majority remains unclear. This XMM-Newton observation will allow us
to carry out a detailed spectral analysis of a very faint transient (< 10
performed so far) in order to (i) shed light on the nature of this growing
population and (ii) the reason for their sub-luminous behaviour.

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.
