We propose observations of two fields in Serpens and one in Perseus centered onnewly discovered regions of recent star formation. Spitzer IR maps of theregions reveal dense molecular gas and numerous previously unknown PMS stars,diverse in both mass and age. Comparison of the IR disk and X-ray coronalproperties will allow detailed characterization of the individual stars andinvestigation of evolutionary trends in different regions. Young stars arestrong X-ray emitters throughout their PMS evolution, from embedded protostarsto older dust-free PMS stars. X-ray emission provides an excellent method oftracing the entire PMS population and investigating the star formation historiesof these regions and the processes controlling the fragmentation and formation of stars.

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.
