cds-question@unistra.frmagellanic-cloudsstellar-associationsWhether or not the rich star cluster population in the Large Magellanic Cloud (LMC) is affected by significant disruption during the first few x10^8^yr of its evolution is an open question and the subject of significant current debate. Here, we revisit the problem, adopting a homogeneous data set of broad-band imaging observations. We base our analysis mainly on two sets of self-consistently determined LMC cluster ages and masses, one using standard modelling and one which takes into account the effects of stochasticity in the clusters' stellar mass functions. On their own, the results based on any of the three complementary analysis approaches applied here are merely indicative of the physical conditions governing the cluster population. However, the combination of our results from all three different diagnostics leaves little room for any conclusion other than that the optically selected LMC star cluster population exhibits no compelling evidence of significant disruption - for clusters with masses, M_cl_, of log(M_cl_/M_{sun}_)>~3.0-3.5 - between the age ranges of [3-10 and 30-100]Myr, either 'infant mortality' or otherwise. In fact, there is no evidence of any destruction beyond that expected from simple models just including stellar dynamics and stellar evolution for ages up to 1Gyr. It seems, therefore, that the difference in environmental conditions in the Magellanic Clouds on the one hand and significantly more massive galaxies on the other may be the key to understanding the apparent variations in cluster disruption behaviour at early times.2013MNRAS.436..136Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/436/136CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/128/1606 : MCPS: the LMC (Zaritsky+, 2004)J/MNRAS/389/678 : Extended objects in Magellanic Clouds (Bica+, 2008)J/A+A/517/A50 : Young SMC/LMC star clusters ages + luminosities (Glatt+ 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/436/136https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/436/136http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/436/136https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/436/136https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/436/136http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/436/136GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/436/136/table1 (LMC cluster positions and derived parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/436/136/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/436/136/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/436/136/table1?GETtext/xml+votable180.050000true71.1958333-69.6421750.0055555555555555565/8269 8274 8280 6/33051 33053-33055 33073-33075 33084 33091 33094-33095 33100-33102 33106-33107 33112 33126 33129https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/436/136?format=asciiOpticaldefaultJ/MNRAS/436/136/table1LMC cluster positions and derived parametersNameCluster name(s)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
