The Star Clusters of the Small Magellanic Cloud: Structural Parameters
We present structural parameters for 204 stellar clusters in the Small Magellanic Cloud derived from fitting King and Elson, Fall, & Freeman model profiles to the V-band surface brightness profiles as measured from the Magellanic Clouds Photometric Survey images. Both King and EFF profiles are satisfactory fits to the majority of the profiles although King profiles are generally slightly superi...
متن کاملThe Star Clusters of the Small Magellanic Cloud: Age Distribution
We present age measurements for 195 star clusters in the Small Magellanic Cloud based on comparison of integrated colors measured from the Magellanic Clouds Photometric Survey with models of simple stellar populations. We find that the modeled nonuniform changes of cluster colors with age can lead to spurious age peaks in the cluster age distribution, that the observed numbers of clusters with ...
متن کاملWfpc2 Observations of Star Clusters in the Magellanic Clouds. Ii. the Oldest Star Clusters in the Small Magellanic Cloud
We present our analysis of archival Hubble Space Telescope Wide Field Planetary Camera 2 (WFPC2) observations in F450W (∼B) and F555W (∼V ) of the intermediate-age populous star clusters NGC 121, NGC 339, NGC 361, NGC 416, and Kron 3 in the Small Magellanic Cloud. We use published photometry of two other SMC populous star clusters, Lindsay 1 and Lindsay 113, to investigate the age sequence of t...
متن کاملSurface brightness profiles and structural parameters for 10 rich stellar clusters in the Small Magellanic Cloud
As a follow up to our recent study of a large sample of LMC clusters (Mackey & Gilmore 2002), we have conducted a similar study of the structures of ten SMC clusters, using archival Hubble Space Telescope snapshot data. We present surface brightness profiles for each cluster, and derive structural parameters, including core radii and luminosity and mass estimates, using exactly the same procedu...
متن کاملOn the Interpretation of the Age Distribution of Star Clusters in the Small Magellanic Cloud
We re-analyze the age distribution (dN/dt) of star clusters in the Small Magellanic Cloud (SMC) using age determinations based on the Magellanic Cloud Photometric Survey. For ages younger than 3×10 yr the dN/dt distribution can be approximated by a power-law distribution, dN/dt ∝ t , with −β = −0.70±0.05 or −β = −0.84±0.04, depending on the model used to derive the ages. Predictions for a clust...
