BS196: an old star cluster far from the Small Magellanic Cloud main body.

Abstract (from CDS):

We present B and V photometry of the outlying Small Magellanic Cloud (SMC) star cluster BS196 with the 4.1-m SOAR telescope. The photometry is deep (to V~25), showing ~3 mag below the cluster turnoff point at MV= 2.5 (1.03M☉). The cluster is located at the SMC distance. The colour-magnitude diagram and isochrone fittings provide a cluster age of 5.0±0.5Gyr, indicating that this is one of the 12 oldest clusters so far detected in the SMC. The estimated metallicity is [Fe/H] = -1.68±0.10. The structural analysis gives by means of the King profile fittings a core radius Rc= 8.7±1.1arcsec (2.66±0.14pc) and a tidal radius Rt= 69.4±1.7arcsec (21.2±1.2pc). BS196 is rather loose with a concentration parameter c = 0.90. With MV = -1.89±0.39, BS196 belongs to the class of intrinsically fainter SMC clusters, which have started to be explored as compared to the well-known populous ones.
