Title XMM study of the emission lines of the Z-Source GX 349+2

Description We propose a 40 ks XMM observation of the Z source GX 349+2, to perform a detailed study of the iron K-shell features and other low energy features in this source. In particular this source is known to show a broad (0.7 keV FWHM) iron K_a line: several hypothesis were proposed to explain the width of these lines (relativistic and Doppler effects in an accretion disk, Compton scattering, line-blending), and we expect that the good energy resolution of XMM will be able to resolve the complex line shape and to constrain the various models proposed. Furthermore, since some emission lines were already observed in GX 349+2 with BeppoSAX below 3 keV, a proper study of these low energy features are an important diagnostic tool for the physical conditions of the emitting regions.

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.
