Abstract	We propose a 30 ks XMM observation of 4U 1728-34 to perform a detailed study ofthe iron K-alpha line and other low energy features. This source shows a broad(~1 keV FWHM) iron line: several hypotheses can be proposed to explain the linewidth (e.g. relativistic and Doppler effects in an accretion disk, Comptonscattering, line-blending), and we expect that XMM will be able to resolve thecomplex line shape and to constrain the various models proposed. These kind ofsources are also expected to be rich of emission lines and absorption edges atlow energy (below ~2 keV), because of the presence of a photoionized accretiondisk corona (ADC). These low energy features are an important diagnostic toolfor the physical conditions of the emitting regions.

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.
