Bridging the dMe Gap with Ross 154

M dwarf flare (dMe) stars provide excellent laboratories for the study ofmagnetic flaring activity, coronal heating, and chemical fractionationmechanisms. Quiescent element abundances seem to be tied to the first ionizationpotential (FIP), but the nature of that dependence varies with the stellaractivity level, whether the emission is quiescent or flaring, and other factors.Understanding flare abundances is important because much of coronal quiescent.emission is likely the result of continuous Xclass microflares.. Only eightlatetype dMe systems have been studied using XMM or Chandra gratings, and alarge gap exists between low and highactivity versions of those stars that canonly be bridged with an observation of Ross 154. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
