J/AJ/134/1298    CaII equivalent widths in 29 Galactic clusters (Carrera+, 2007)

The infrared Ca II triplet as metallicity indicator. Carrera R., Gallart C., Pancino E., Zinn R. <Astron. J., 134, 1298-1314 (2007)> =2007AJ....134.1298C
ADC_Keywords: Clusters, open ; Clusters, globular ; Stars, giant ; Equivalent widths ; Radial velocities Keywords: globular clusters: general - open clusters and associations: individual (Berkeley 39, Collinder 110, Trumpler 5) - stars: abundances - stars: late-type Abstract: From observations of almost 500 red giant branch stars in 29 Galactic open and globular clusters, we have investigated the behavior of the infrared Ca II triplet (8498, 8542, and 8662Å) in the age range 13Gyr≤age≤0.25Gyr and the metallicity range -2.2≤[Fe/H]≤+0.47. These are the widest ranges of ages and metallicities in which the behavior of the Ca II triplet lines has been investigated in a homogeneous way. We report the first empirical study of the variation of the Ca II triplet lines' strength, for given metallicities, with respect to luminosity. Description: About 500 stars have been observed in the 29 clusters of our sample in six different runs from 2002 to 2005, using the WHT and the INT, both at Roque de los Muchachos Observatory (La Palma, Spain); the 4m telescope at CTIO (La Serena, Chile); the 2.2m telescope at the Calar Alto Observatory (Almeria, Spain); and the VLT at Paranal Observatory (Chile).
