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).
