Title GBS-discovered quiescent X-ray binaries: XMM eclipse duration and VLT spectra

Author Dr Peter Jonker
Description We propose to use XMM to observe eclipsing probable quiescent low-mass X-ray binaries selected from the Galactic Bulge Survey. The XMM data are crucial to determine the eclipsing duration, one cannot do this as accurately from optical light curves because optical emission regions tend to be virgul1-3 of the orbital separation whereas X-ray emission regions only 1-100th, making X-ray eclipses sharp while optical eclipses are ..fuzzy.. Using the XMM eclipse duration and the VLT spectroscopy we can determine virtually model independent masses of the compact objects. Furthermore, we may select different mass ratio systems favoring low-mass black holes.

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.
