|Title||X-ray emission from protostars in the NGC1333 and Serpens star forming regions|
|Author||Dr Thomas Preibisch|
|Description||We propose 50 ksec EPIC-pn observations of the NGC 1333 and the Serpens star forming regions to search for X-ray emission from the numerous deeply embedded protostars in these most nearby (300 pc) protocluster regions, apart from Rho Oph. Strong X-ray emission from two highly obscured objects in these regions was detected with ROSAT, and an ASCA image indicated the presence of several other (still unidentified) optically invisible X-ray sources in NGC 1333. Due to its unique sensitivity for hard X-rays, XMM will be able to reveal new embedded objects suffering extinctions of up to Av = 500 mag, totally obscured in soft X- rays (i.e. for ROSAT). XMM studies of protostars will open up a new door to learn more about the role of magnetic fields in star-, disk-, and jet-formation.|

|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.
