XB 1323-619 is a stable dipping LMXB which has uniquely quasi-periodic burstingresulting in a new phenomenon: regular occurence of bursts in dips whenouter accretion disk is highly ionized. XMM will for the 1st time allowthis to be used as a novel diagnostic of bursts and giving electrondensity and ionization state in outer disk. Spectral analysis of complexdip evolution reveals the nature of emission regions allowing for the 1sttime testing whether the blackbody arises on neutron star or accretiondisk; rejection of the latter has important consequences. We can alsomake a detailed study of burst evolution (out of dips). XMM can test whether

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.
