Scientific paper

We propose 20 ks pointings with Chandra HRC-I to obtain detections of two red giants in the depths of the "coronal graveyard." Our program will test the hypothesis that significant coronal activity persits on the red giants, but smothered beneath a "cool absorber" in the chromospheric envelope. Such activity might be the long-sought initiator of red giant winds. HST/STIS E140M spectra are proposed for one of the targets-alpha Tau {K5 III}; to help probe conditions in the cool absorber. High-S/N STIS spectra already are available for the other target, alpha Boo {K2 III}.
