J/AJ/140/1694  Abundances of non-variable red and blue HB stars (For+, 2010)

The chemical compositions of non-variable red and blue field horizontal branch stars. For B.-Q., Sneden C. <Astron. J., 140, 1694-1718 (2010)> =2010AJ....140.1694F
ADC_Keywords: Stars, horizontal branch ; Abundances ; Equivalent widths Keywords: stars: abundances - stars: horizontal-branch Abstract: We present a new detailed abundance study of field red horizontal branch (RHB) and blue horizontal branch (BHB) non-variable stars. High resolution and high signal-to-noise ratio echelle spectra of 11 RHB and 12 BHB were obtained with the McDonald 2.7m telescope, and the RHB sample was augmented by reanalysis of spectra of 25 stars from a recent survey. We derived stellar atmospheric parameters based on spectroscopic constraints and computed relative abundance ratios for 24 species of 19 elements. Description: The observations were made with the McDonald 2.7m Smith telescope, using the Tull "2dcoude" cross-dispersed echelle spectrograph. Optimall spectral coverage was obtained for observing run in 2009. File Summary:
