|Title||XMM observations of a sample of bright Atoll sources|
|Author||Prof Andrea Santangelo|
|Description||We propose a XMM observational campaign on a sample of three bright atoll LMXRBs. Primary scientific goal is the study of the broad Iron K alpha feature to deeply understand its relativistic diskline origin while exploring alternative models based on thermal Comptonization broadening. We request a total of 150 ksec(50 ks on each source) to be performed for two sources in pn timing mode and for one source in modified pn timing mode for which calibration and new response matrices have been obtained by our group. Based on the capability of the RGS, a second science objective of the proposal is the study of the low energy spectrum to search for broad emission and-or absorption features (due to ionized O, N, Ne, Fe) similar to the ones observed in other systems.|

|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.
