ROSAT Observations of alpha TrA and IOTA AUR
Abstract
We report here on pointed ROSAT observations of the hybrid chromosphere stars alpha TrA (K4III) and iota Aur (K3II). We detect alpha TrA at signal-to-noise greater than 50, and iota Aur marginally. The column density of absorption of X-rays from alpha TrA is consistent with IUE observations. We also see a flare type event in its lightcurve. Finally, we find that the X-ray emission from alpha TrA is mostly from plasma at temperatures greater than 1 keV.
