J/A+A/503/469       Compact clusters in LMC catalogue of stars      (Liu+, 2009)

The low-mass stellar-mass functions of rich, compact clusters in the Large Magellanic Cloud. Liu Q., de Grijs R., Deng L.C., Hu Y., Beaulieu S.F. <Astron. Astrophys. 503, 469 (2009)> =2009A&A...503..469L
ADC_Keywords: Magellanic Clouds ; Clusters, globular ; Photometry, HST Keywords: stars: low-mass, brown dwarfs - stars: luminosity function, mass function - stars: pre-main sequence - Magellanic Clouds - galaxies: star clusters Abstract: The LMC is an ideal environment for studying stellar MFs, because it contains a large population of compact clusters at different evolutionary stages. We aim to obtain constraints on the initial MFs (IMFs) of our sample clusters on the basis of their present-day MFs, combined with our understanding of their dynamical and photometric evolution. We use Hubble Space Telescope photometry for six rich, compact star clusters in the Large Magellanic Cloud (LMC), with ages ranging from 0.01 to 1.0Gyr, to derive the clusters' stellar mass functions (MFs) at their half-mass radii. Description: The compact clusters in LMC Catalogue of Stars is based on HST/WFPC2 and HST/STIS observations for six compact clusters in the Large Magellanic Cloud.
