We present the X-ray flaring properties from a unique, 7-day multiwavelength “high-time resolution” observing campaign on the M1 flare star AU Mic. The X-ray spectral evolution and line broadenings of Hα and Hβ lines are discussed and compared with the solar flare standard model and RADYN code modeling. The results suggest that these most energetic M-dwarf flares are associated with stronger magnetic field flux densities and larger size scales than solar flares but can be interpreted in terms of the solar flare standard flare model.
