Abstract

The RS CVn binaries have been found to be a new class of soft x-ray sources from the HEAO 1 low energy sky survey¹. We discuss here a star with RS CVn-type characteristics that was discovered as a result of an accurate x-ray location². We have detected this source at energies<1 keV and present evidence for variability on time scales ~1 day. Subsequent spectrophotometry revealed variable Hα and possibly Ca II H, K emission which strongly supports its classification as an RS CVn system.
