Title The nature of magnetic activity at the low-mass end of the main-sequence

Author Dr Beate Stelzer
Description We propose for XMM-Newton observations of 5 carefully selected ultracool dwarfs, jointly with the E-VLA and Halpha monitoring, to systematically investigate magnetic activity in late-M dwarfs. Our targets are nearby (<20 pc), known to maintain magnetic fields (direct field detections), they yield evidence for chromospheres (Halpha emission) and have known rotation rate (v sini). This will allow us to study the connection between chromospheric and coronal activity, their relation with rotation, and possibly study the dynamics of flares at the bottom of the main-sequence. This proposal has been downscaled from an LP submitted to AO10 in order to accomodate the TAC request to make the multi- wavelength observations simultaneous which would be unfeasible for a much larger sample.

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.
