XMM observations of a sample of bright Atoll sources
Abstract
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.
