Abstract:
We present for the first time Washington CT1 photometry for 11
unstudied or poorly studied candidate star clusters. The selected
objects are of small angular size, contain a handful of stars, and are
projected towards the innermost regions of the Small Magellanic Cloud
(SMC). The respective colour-magnitude diagrams (CMDs) were cleaned
of the unavoidable star field contamination by taking advantage of a
procedure which makes use of variable size CMD cells. This method has
shown to be able to eliminate stochastic effects in the cluster CMDs
caused by the presence of isolated bright stars, as well as to make a
finer cleaning in the most populous CMD regions. Our results suggest
that nearly one-third of the studied candidate star clusters would
appear to be genuine physical systems.
Description:
Piatti (2012MNRAS.422.1109P 2012MNRAS.422.1109P) performed reduction, stellar photometry
and photometric standardization of Washington CT1 images of 11 SMC
fields obtained at the Cerro Tololo Inter-American Observatory 4-m
Blanco telescope with the Mosaic II camera attached (36x36arcmin2
field on to a 8Kx8K CCD detector array). Here we give informations for
B119.
