CaII equivalent widths in 29 Galactic clusters
Listed in IVOA Registry (Virtual Observatory)
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 8662{AA}) in the age range 13Gyr<=age<=0.25Gyr and the metallicity range -2.2<=[Fe/H]<=+0.47.
Description
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.
