Abstract:
Fine analyses of the silicon stars HD 133029 and HD 192913 are
presented using ATLAS9 model atmospheres whose predictions fit the
optical region spectrophotometry and Hγ profiles and have the
same bulk metallicity as the deduced abundances. Both are very He poor
stars. The light elements are mostly solar except for silicon, and all
the heavier elements, except nickel in HD 133029 which is solar, are
greatly overabundant. The iron peak elements are typically 10 times
overabundant. SrYZr are of order of 100 times solar. The rare earths
are 1000 or more times overabundant.
