Abstract	We propose a 50 ksec XMM-Newton observation of a massive stellar binary WR30a.The binary consists of a WO-type Wolf-Rayet star and an O type companion. AWO-type star is generally thought to be the final evolutionary stage in the WRphase, and has the fastest stellar wind with average terminal velocity approx5000 km s-1. To date, there is no report on X-ray detection from WO-type stars,while intensive studies have been made for WN- and WC- type stars with X-rays.Our aim is to detect X-rays from a WO-type binary for the first time, and tocompare the X-ray properties (especially the plasma temperature) with those ofwell-researched two types (WN and WC).

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.
