| Abstract | We aim to determine the frequency and characteristics of X-ray emission from RVTau variables stars. Only one RV Tau variable star has been targeted by modernX- ray observatories and its detected X-ray emission is surprising and difficultto understand. We request 140 ks to study a pilot sample of four RV Tau variablestars in order to establish if X-ray emission is ubiquitous amongst theseluminous and pulsating stars. The requested observations would determine thecharacteristics of any X-ray emission and help identify the origin of the X-rayemission. As known and suspected binary systems, discovering X-ray emission fromthese stars can open new windows into binary evolution at their intermediatestages. |

| 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. |
