Abstract | Investigating the poorly understood accretion mechanism producing the shortflares observed from the SFXTs is a key tool in placing these X-ray binaries inthe wider context of the HMXBs. Studies of this X-ray binary class arefundamental to understanding the evolution of massive stars, to determining thechemical enrichment of the Galaxy and to give a significant contribution tostudying the neutron star equation of the state. Current theories are basedon a mass transfer via an isotropic and inhomogeneous clumpy wind or viaaccretion from anisotropic supergiant wind or on the high magnetic field ofneutron stars (>10^14 G) regulating the duration and peak luminosity of theoutbursts.Outbursts of IGR J16328-4726 occur at a restricted phase range |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
