We propose to observe the eclipsing Algol-type system RZ Cas with XMM-Newton.Simultaneous observations with the radio VLA will be requested. Thanks to itsshort rotational and orbital period (P = 1.195d), a 110 ksec observation willcover the whole binary phase. We will address the following issues: i\) theeclipse of the late-type component (K3IV) by the non-magnetic primary (A3V) willbe monitored in the X-ray and radio ranges, allowing us to reconstruct andcompare the geometry of the corona of the magnetically active star in thethermal and non-thermal regimes; ii\) signatures for accretion flow materialwill be looked for, in particular an excess absorption column density; iii\) the primary eclipse will provide constraints on the emission from the A star.

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.
