cds-question@unistra.frgalaxiesglobular-star-clustersgalaxy-classification-systemsphotometryThe structures of globular clusters (GCs) reflect their dynamical states and past histories. High-resolution imaging allows the exploration of morphologies of clusters in other galaxies. Surface brightness profiles from new Hubble Space Telescope observations of 34 GCs in M31 are presented, together with fits of several different structural models to each cluster. M31 clusters appear to be adequately fit by standard King models and do not obviously require alternate descriptions with relatively stronger halos, such as are needed to fit many GCs in other nearby galaxies. The derived structural parameters are combined with corrected versions of those measured in an earlier survey in order to construct a comprehensive catalog of structural and dynamical parameters for M31 GCs with a sample size similar to that for the Milky Way. Clusters in M31, the Milky Way, Magellanic Clouds, the Fornax dwarf spheroidal, and NGC 5128 define a very tight fundamental plane with identical slopes. The combined evidence for these widely different galaxies strongly reinforces the view that old GCs have near-universal structural properties, regardless of host environment.2007AJ....133.2764Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/2764CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/119/727 : M31 globular clusters photometry (Barmby+, 2000)J/AJ/123/2490 : RV and [Fe/H] of M31 globular cluster system (Perrett+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/2764https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/2764http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/2764https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/2764https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/2764http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/2764GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/133/2764/table1 (Integrated measurements for M31 clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/2764/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/2764/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/2764/table1?GETtext/xml+votable180.050000true10.3957541.24855560.0055555555555555566/2621 2622 2623 2666 2667 2704 2708 2709 2710 2752https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/133/2764?format=asciiOpticaldefaultJ/AJ/133/2764/table1Integrated measurements for M31 clustersrecnoRecord number assigned by the VizieR team.
