Descripción
We present observations for three star clusters, Kron 11, Kron 63 and
NGC 121, in the Small Magellanic Cloud. We have studied their structure
and derived their fundamental parameters by means of their luminosity
functions, their colour magnitude diagrams and the Padova suite of
isochrones. NGC 121 is a well-studied object, for which we confirm
previous evidence about its old age and low-metal content, and have
found that it is an undergoing mass segregation. Kron 11 and Kron 63 are
poorly populated clusters which had never been studied so far. Kron 11
is several gigayears younger than NGC 121, while Kron 63 is basically a
very young star aggregate. Both clusters are immersed in dense stellar
fields which share the same population properties, suggesting that in
their cases, cluster ages are consistent with typical ages of field
stars.
