|Title||Meet the parents: tracing star formation around the ρ Ophiuchi star.|
|Author||Dr Ignazio Pillitteri|
|Description||Understanding the mechanisms that trigger the star formation is of crucial importance both in the solar neighborhood and in more distant places. We propose an XMM-Newton observation to study a possible case of triggered star formation event in the nearby star forming region hosting the Rho Ophiuchi star. The suburbs 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 those in the main cloud core. Once knowing the sample of stars with and without disk we can estimate the age and assess the evolutionary stage of this part of the cloud and then trace its star formation history.|

|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.
