Abstract Open Cluster Remnants (OCRs) are poorly populated groups of stars in an advancedstage of the evolution of open clusters. They are especially rich in late-typestars and binary systems of stars, of which a fraction is expected to beinteracting binaries (RS CVn, cataclysmic variables, and low-mass X-raybinaries). We propose to investigate the X-ray content of the OCR NGC 1901,looking for signatures of accreting/interacting binary systems and active starsin order to put constraints on the evolutionary models describing the finalstages of star clusters.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
