Abundances of light elements in metal-poor stars II. Non-LTE abundance corrections
We present non-LTE corrections to abundances of Fe, O, Na, and Mg derived from LTE analyses of F-K stars over a broad range of gravities and metal abundances; they were obtained using statistical equilibrium calculations and new model atoms. Line opacity was considered by means of an empirical procedure where it was attributed to a veil of weak Fe I lines; in the case of solar-type dwarfs, resu...
متن کاملOXYGEN LINE FORMATION IN LATE-F THROUGH EARLY-K DISK/HALO STARS: INFRARED O i TRIPLET AND [O i] LINES
In order to investigate the formation of O i 7771–5 and [O i] 6300/6363 lines, extensive non-LTE calculations for neutral atomic oxygen were carried out for wide ranges of model atmosphere parameters, which are applicable to early-K through late-F halo/disk stars of various evolutionary stages. A useful formula with tabulated numerical coefficients is presented, applicable to evaluating NLTE co...
متن کاملNon-LTE Abundances of Magnesium, Aluminum and Sulfur in OB Stars Near the Solar Circle
Non-LTE abundances of magnesium, aluminum and sulfur are derived for a sample of 23 low-v sin i stars belonging to six northern OB associations of the Galactic disk within 1 kpc of the Sun. The abundances are obtained from the fitting of synthetic line profiles to high resolution spectra. A comparison of our results with HII region abundances indicates good agreement for sulfur while the cephei...
متن کاملNon-LTE analysis of neutral magnesium in cool stars
Calculations of the statistical equilibrium of magnesium in the solar photosphere have shown that NLTE populations hardly affect Mg line formation in the Sun. However, in metal-poor dwarfs and giants the influence of electron collisions is reduced, and the ultraviolet radiation field, enhanced due to reduced background line opacity, results in more pronounced NLTE effects. In the photosphere of...
متن کاملC Ii Abundances in Early-type Stars: Solution to a Notorious Non-lte Problem
We address a long-standing discrepancy between non-LTE analyses of the prominent C ii λλ4267 and 6578/82Å multiplets in early-type stars. A comprehensive non-LTE model atom of C ii is constructed based on critically selected atomic data. This model atom is used for an abundance study of six apparently slow-rotating main-sequence and giant early B-type stars. High-resolution and high-S/N spectra...
