The fate of binary or multiple systems can be violent merger events with massexchange and the ejection of large scale outflows. One of the most recentlydiscovered merger candidates is our target, TYC 597-735-1, which harbors a bluering nebular surrounding the rapidly rotating central source. A short,serendipitous Chandra observation suggests three X-ray sources associated withTYC 597-735-1. Here, we propose a 50 ks follow-up observation to uncover theorigin of the X-ray emission, magnetic activity or shocks, as both scenarioshave strong implications for the evolution of stellar merger remnants.

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.
