Description M dwarf flares exhibit a strong response in the X-ray and NUV, in line with the Neupert effect. However, some flares produce only bright X-rays and others only a bright NUV response. Our fundamental understanding of stellar flares is therefore hampered by the lack of multi-wavelength data. We propose a large XMM campaign to determine the origin of Neupert versus non-Neupert flares in AU Mic. The timing, amplitude, and atmospheric parameters of the flares will determine whether the differences are related to the relative roles of proton and electron beam heating. This study will also constrain the high-energy tail of AU Mic.s flare frequency and hence enable a test of whether the system.s debris disk is experiencing space-weather.

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.
