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

| 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. |
