|Title||The dwarfs of the Ring: Star Formation around Kappa Ori explored with XMM-Newton|
|Author||Dr Ignazio Pillitteri|
|Description||One of the mechanisms proposed for causing the collapse of a gas cloud and start star formation is the action of an external agent that can compress the gas and create the primordial protostellar cores (Elmegreen 1998). While supernovae are the most dramatic agents, stellar winds from massive stars and the expansion of ionized HII bubbles may play an important role. They can transfer momentum, kinetic energy and heat a close-by gas cloud. A few cases have been identified where massive stars are responsible of triggered star formation (RCW79, Zavagno et al. 2006, Sharpless 104, Deharveng et al., 2003). With this XMM proposal, we aim to understand the interaction at work between one single massive star, Kappa Ori, and Lynds 1641 (L1641), the filamentary cloud in the southern part of the Orion~A cloud.|

|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.
