GT Observations of Active Cool Stars: AT Mic

GTAT Mic is an Xray luminous M dwarf binary system, consisting of two almostidentical flare stars. Energetic flares have been observed previously. Wepropose to observe AT Mic to investigate its abundance and temperaturestratification, and search for temperature dependent densities and abundances.Smallscale flare variability will be looked for, and larger flares will beanalyzed in terms of temperature, density, velocity, and abundance historieswith the RGS and the EPICs. Simultaneous radio VLA/VLBA observations will berequested to investigate flare energy release. One EPIC MOS and the pn camerawill be operated in TIMING mode with the medium filter to optimize for flares.The OM will use the UVW1 filter. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
