Abstract We propose for XMM-Newton observations of young Brown Dwarfs (BD) and BrownDwarf Candidates (BDC) in the Taurus star forming region. In order to probemagnetic activity in the substellar regime we plan to observe four objects ofdifferent spectral type, i.e. mass, from M6 to M8. This will shed light on therelation between bolometric and X-ray luminosity. Together with photometricobservations we will be able to test the rotation-activity connection, as wellas the influence of accretion onto magnetic activity. These relations arecrucial to determine the nature of the dynamo in fully convective objects. YoungBDs are particularly suited for such studies because they are luminous.Comparison to old field BDs will allow to constrain the evolution of activity for very low-mass objects.

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.
