COOL PROMINENCES IN THE CORONA OF THE RAPIDLY ROTATING DME STAR, HK AQUARII

We report the discovery of cool, prominence-like material embedded in the hot corona of the rapidly rotating dMe flare/spot variable, HK Aqr . Using these observations we demonstrate that, unlike the case of the rapidly rotating K dwarf, AB Dor, these features form well below the co-rotation radius. Rather they have dimensions between 3-20 times tho se of the very largest solar prominences. At least seven clouds were d etected during each stellar rotation and they have a lifetime of great er than the three nights spanned by our data.
