Algol is a triple system containing a 70 hr eclipsing binary (K IV and B8 V) in a 694 day orbit with an A V star. The X-ray emission from this system (Schnopper et al 1976) is thought to be associated with a corona surrounding the lobe filling and synchron- ously rotating K IV star. This is based on the similarity of the X-ray spectrum and luminosity of this system to that of the RS CVn binaries which also contain K sub-giants with similar rotation periods and the fact that the luminosity of any coronae surrounding the B8 V and AV companion stars should not be enhanced by rapid rotation...
