| Abstract: |
We present initial results from coordinated, multi-wavelength monitoring of two nearby dMe flare stars: EQ Pegasi and AU Microscopii. Our primary goal was to observe the impulsive and cooling phases of stellar flares. AU Mic was observed 1996 June 12-15 with the RXTE and EUVE satellites. EQ Peg was observed 1996 October 2-6 with RXTE, EUVE, the ubvr photometer on the McDonald Observatory 0.9-m telescope, and the VLA at 3.5 and 20 cm. We present light curves in most observed wavebands and X-ray spectra obtained during flares and quiescence. Although a number of moderately polarized VLA radio flares are seen, there is no compelling evidence in the RXTE data for hard, non-thermal X-ray emission. We also discuss an extreme ultraviolet transient event detected by ALEXIS on 1996 June 15 in the direction of AU Mic. |
