Abundance analyses of cool extreme helium stars

Pandey, Gajendra; Rao, N.Kameswara; Lambert, David L; Jeffery, C.Simon; Asplund, Martin

Description

<P> Extreme helium stars (EHes) with effective temperatures from 8000 to 13000K are among the coolest EHes and overlap the hotter R CrB stars in effective temperature. The cool EHes may represent an evolutionary link between the hot EHes and the R CrB stars. Abundance analyses of four cool EHes, BD+1˚4381 (FQ Aqr), LS IV -14˚109, BD -1˚3438 (NO Ser) and LS IV -1˚002 (V2244 Oph), are presented. All these stars show evidence of H- and Heburning at earlier stages of their evolution. <P> To test...[Show more]
