A Unified Understanding of Flare Heating
Abstract
M dwarf flares exhibit a strong response in the X-ray and NUV, in linewith the Neupert effect. However, some flares produce only bright X-raysand others only a bright NUV response. Our fundamental understanding ofstellar flares is therefore hampered by the lack of multi-wavelengthdata. We propose a large XMM campaign to determine the origin ofNeupert versus non-Neupert flares in AU Mic. The timing, amplitude,and atmospheric parameters of the flares will determine whether thedifferences are related to the relative roles of proton and electronbeam heating. This study will also constrain the high-energy tail of AUMic's flare frequency and hence enable a test of whether the system'sdebris disk is experiencing space-weather.
