VizieR Online Data Catalog: Parameters of HB stars in ω Cen (Moni Bidin+, 2012)
Abstract
Our observations targeted 115 HB stars in ω Cen, selected from the optical photometry of Bellini et al. (2009, Cat. J/A+A/493/959). The data were collected at the Paranal Observatory in service mode, with the FORS2 spectrograph mounted on the UT1 telescope, in 2006 from January to April. The temperatures, gravities, and surface helium abundances were derived fitting the Balmer and helium lines with synthetic model spectra. Reddening and mass were estimated from these parameters.
