XMM-Newton and the Pleiades - I. Bright coronal sources and the X-ray emission from intermediate-type stars.
BRIGGS K.R. and PYE J.P.
Abstract (from CDS):
Spectral modelling of the quasi-steady emission shows a rising trend in coronal temperature from F and slowly rotating G stars to K stars to fast-rotating G stars, and a preference for low coronal metallicity. These features are consistent with those of nearby solar-like stars, although none of the three stars showing `saturated' emission bears the significant component at 2 keV seen in the saturated coronae of AB Dor and 47 Cas. Of five intermediate-type stars, two are undetected (LX< 4x1027 erg/s) and three show X-ray emission with a spectrum and L Xconsistent with origin from an active solar-like companion.
