Abstract:
Colour-magnitude diagrams in the Washington system are presented for
the first time for five star clusters projected on to the outer region
of the Small Magellanic Cloud (SMC). The clusters are found to have
ages in the range 0.1-1.0Gyr, as derived from the fit of isochrones
with Z=0.004. This sample increases substantially the number of
young clusters in the outer SMC - particularly in the south-east
quadrant - with well-derived parameters. We combine our results with
those for other clusters in the literature to derive as large and
homogeneous a data base as possible (totalling 49 clusters) in order
to study global effects.
Description:
The CCD images were obtained using the 1.54-m Danish telescope at the
European Southern Observatory (ESO) on La Silla, equipped with the
Danish Faint Object Spectrograph and Camera (DFOSC) on 4-5 Nov and
29 Dec 1999. Observations were secured in the Washington C and
Kron-Cousins R filters.
