|Title||V838 Mon: A Search for X-rays from a Possible Stellar Merger|
|Author||Prof Joel Kastner|
|Description||V838 Mon is perhaps the most enigmatic and unusual object observed in stellar astrophysics in recent decades. The star underwent an enormous outburst in 2002, resulting in a spectacular system of light echoes whose evolution has been well documented by HST. The cause of the outburst remains the subject of vigorous debate. One possibility is that of a stellar merger. A prediction of this model is that the envelope of the merger remnant should be magnetically active. If so, V838 Mon should be a luminous X-ray source. We propose a 100 ks XMM-EPIC observation that will constrain the merger model for the V838 Mon outburst and will help characterize the young cluster in which V838 Mon resides.|

|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.
