Abstract	The spectral type boundary that determines which very low-mass objects willeventually become M stars, vs. brown dwarfs, remains poorly constrained duringpre-main sequence evolution. High-energy observations of pre-main sequence Mstars offer a means to probe chromospheric and coronal activity due to stellarmagnetic activity, so as to help determine this boundary. However, even though amajority of stars in the solar neighborhood are of mid- to late-M type, theX-ray activity of such stars remain essentially unexplored for the important agerange 10-100 Myr. We propose to use XMM-Newton to observe 9 nearby (D~50 pc),young (age 10-100 Myr) stars of type M4-M9, to investigate the potentialdecrease in UV and X-ray luminosities for very low-mass stars at this age.

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.
