Cool Stars 14 - Submitted Abstract # 181 This version created on 05 October 2006 The recombining flaring plasma of EV Lac Urmila Mitra-Kraev, University of Sheffield, UK Jan-Uwe Ness, Arizona State University, USA We present the pure flaring spectrum of the active M-type star EV Lac, as observed by the Chandra observatory in the X-ray range 1.8--26 Angstroms. While, as expected, the flaring spectrum is dominated by hotter lines than the quiescent one, we also find that certain line ratios of the flaring spectrum are incompatible with a "coronal" plasma in thermal equilibrium. However, they are consistent with a highly ionized, rapidly cooling plasma. These findings have major consequences for interpreting the plasma of active stellar coronae. In particular, such thermal non-equilibrium conditions lead to a suppression of the resonance line of O VII and affects the G-ratio, which is often used for temperature diagnostics in collisionally ionized plasma in thermal equilibrium. Inconsistencies between the temperature derived from the G-ratio and temperatures derived by other means can thus be solved, as the flaring plasma is no longer in thermal equilibrium. We also find hugely enhanced densities in the flaring plasma. ----------------------------------
