Description A0538-66 is a Be-X-ray binary (XRB) containing a 69ms pulsar that shows bright X-ray outbursts at periastron (up to 1E39 erg-s) associated with luminous optical flares (up to one order of magnitude brighter than the companion star luminosity). Optical flares reaching these luminosities are not observed in other Be-XRBs. We propose three observations of A0538-66, each 10 ks long, during three periastron passages of the neutron star, to understand the mechanism responsible for the production of fast and bright optical flares, and to search for pulsations never observed again after Einstein.s detection. We will use EPIC, OM, and simultaneous optical to near-infrared observations from our on-going REM monitoring.

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.
