Abstract PV- YY Gem is a close, fully eclipsing binary dMe binary with a period of 0.81d.Both the primary and the secondary eclipses show deep X-ray minima. At adistance of 71 arcsec, the quadruple system of Castor A+B is another X-raysource. This observation will be used to perform i) phase resolved spectroscopyduring a 1 d period; eclipses, flares and rotational modulation will bespectroscopically monitored and modeled; and ii) to perform RGS spectroscopy oftwo sources separated by 71 arcsec. We request position angle constraintsdisplacing the sources along the RGS cross-dispersion direction. The pn camerawill use the SML window/thick filter mode to block optical contamination fromCastor A+B. One MOS will be optimized for the detection of Castor A+B.

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.
