ABSTRACT
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.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
