VizieR Online Data Catalog: The evolutionary status of GK subgiants (Abt, 2019)
Abstract
The Snowden-Young (2005ApJS..157..126S) sample of GK class IV stars north of -20° decl. was selected from the Yale Catalog of Bright Stars (Hoffleit 1964, Cat. V/50). In addition, Snowden & Young observed 14 additional stars as controls. They were GK III standards of radial velocities and three known spectroscopic binaries: HD 102928 (Massarotti et al. 2008, J/AJ/135/209), HD 150680 (Katoh et al. 2013, J/AJ/145/41), and HD 170829 (Katoh et al. 2013, J/AJ/145/41). Most of the new radial velocities of these bright stars were obtained with the 1.53 m Harvard Tillinghast telescope at the Oak Ridge Station. The original digital spectrograph, which gave velocity accuracies of σ~+/-0.3 km/s, was replaced in 2011 with an echelle spectrograph (Tillinghast Reflector Echelle Spectrograph) giving α=+/-0.10 km/s. The individual velocities can be found at http://www.cfa.harvard.edu/~latham/snowden/snowden.orb.
