Understanding the mechanisms that trigger the star formation is of crucialimportance both in the solar neighborhood and in more distant places. We proposean XMM-Newton observation to study a possible case of triggered star formationevent in the nearby star forming region hosting the Rho Ophiuchi star. Thesuburbs of Rho Oph star are depleted of dust and are marked by a warm dust ring.Inside the ring, few young stellar objects with disks are found. Through X-rays,we aim to have a complete census of the disk-less stars more evolved than thosein the main cloud core. Once knowing the sample of stars with and without diskwe can estimate the age and assess the evolutionary stage of this part of thecloud and then trace its star formation history.

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.
