|Title||Enigmatic X-Ray Emission from a Wolf-Rayet Binary Theta Muscae|
|Author||Mr Yasuharu Sugawara|
|Description||We propose a follow-up XMM observation of THETA Muscae with WC star in front. Our primary goal is to identify the location of the Radiative Recombination Continua (RRC) by monitoring the flux change in the difference orbital phase from the previous observation. If the RRC can exist in any binary with a variety of the orbital period, we can expect the RRC is common in WC binary. If the RRC only exists in the short binary with period of an order of 10 days, it strongly restricts the physical parameters, such as density, of the plasma that forms RRC. The RRC is very unique structure to the WC+O binary, which is hardly seen in the other celestial objects.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
