Title Neutron star mass through hydrodynamics in obscured sgHMXB systems

Author Dr Antonios Manousakis
Description Obscured sgHMXB discovered by INTEGRAL are characterized by slow stellar winds. The gravity of the accreting neutron star has therefore an important impact on the wind accretion flow. The variability of the absorbing column density with orbital phase and the long term X-ray variability can be directly compared to the predictions of hydrodynamical models to constrain the mass of the neutron star, with an accuracy of a few tenth of solar mass, and the dynamics of the accretion flow. We propose to observe an eclipsing absorbed sgHMXB with XMM to probe the accretion flow, to obtain an independent measure of the NS mass and to further test our hydrodynamical model.

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.
