|Title||XMM-Newton Survey of Globular Cluster Ultracompact Binaries|
|Author||Prof Deepto Chakrabarty|
|Description||We propose to observe three ultracompact (Porb<80 min) LMXBs in globular clusters, all of which may be members of an emerging class of ultracompact binaries with exotic neon-rich donors. The location of these sources within globular clusters makes them a powerful tool for understanding this class, since basic parameters like distance and ISM absorption are well determined. Our study will (1) measure absorption and emission features and by doing so establish the nature of the donor, and (2) search for X-ray and UV modulations indicative of ultrashort orbital periods.|

|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.
