J/A+A/363/1051      Properties of He-rich stars. III.         (Zboril, 2000)

Properties of He-rich stars. III. Model atmospheres and diagnostic tools. Zboril M. <Astron. Astrophys. 363, 1051 (2000)> =2000A&A...363.1051Z
ADC_Keywords: Models, atmosphere ; Abundances ; Stars, peculiar Keywords: stars - abundances: atmospheres ; chemically peculiar Abstract: We present a study of helium rich atmospheres in the interval He/H 0.1-1.0 as derived from fully consistent model computations for effective temperature (from 15000K up to 32000K) and surface gravity (log(g)=3.5 and 4.0).
