Digging deeper in the coronal graveyard: postscript.
AYRES T.R.
Abstract (from CDS):
An X-ray upper limit–from the ROSAT High Resolution Imager–is presented for ε Corvi (HD 105707), a K2 giant that lies in the ``noncoronal'' zone of the Hertzsprung-Russell diagram, but which previously was detected by the Hubble Space Telescope Goddard High Resolution Spectrograph in far-ultraviolet coronal proxies. The new measurement strengthens the anticorrelation between coronal X-rays and λ1380 carbon monoxide emission among the red giants.
