Age and metallicity of star clusters in the Magellanic Clouds.

DE FREITAS PACHECO J.A., BARBUY B. and IDIART T.

Abstract (from CDS):

Spectral indices as defined by the Lick group (Hβ, Mg2, Fe5270, Fe5335 and NaD) were measured for a sample of 14 clusters in the Magellanic Clouds. Iron and hydrogen indices, together with the integrated colours (B-V) and (V-K) for these clusters, were used to estimate their ages and metallicities, using calibrations based on single stellar population models. The resulting ages and metallicities are in agreement with ages estimated from colour-magnitude diagrams, and metallicities derived from spectroscopic analises or narrow band photometry.
