Scientific paper

We propose to observe the Z source GX 17+2 with XMM-Newton for 40 ks, to perform a detailed study of the iron K-shell feature to assess its origin. A broad emission feature compatible with a highly ionized iron line has been detected both in BeppoSAX and in Chandra observations of the source. The Chandra spectrum suggests that the line might be of relativistic origin, but the large collecting area of XMM-Newton is needed to resolve unambiguously the line profile, which can give important information on the dynamics of accretion and on the structure of neutron stars. Use of the modified timing mode will allow to maximize the time efficiency of the observation and to perform high-statistics timing analysis.
