Abundances in G Dwarfs. V. The Metal-Rich Star 20 Leo Minoris and Two Comparison Stars.
Abstract
We have found 20 LMi to be overabundant in eleven elements by a factor of 2 when compared with the sun. The uncertainties in the analysis admit the possibility that the overabundance is as small as that in the Hyades (25 per cent) to as large as a factor of 3 greater than the sun. The low-velocity star HD 187923 has a slight excess of metals, and the high-velocity star HD 30649 is deficient in metals by a factor of 2. Both HD 187923 and HD 30649 are deficient in manganese relative to the other ten elements studied.
