cds-question@unistra.frglobular-star-clustersvisible-astronomymedium-band-photometrychemical-abundancesWe present a photometric study of M13 multiple stellar populations over a wide field of view, covering approximately 6.5 half-light radii, using archival Isaac Newton Telescope observations to build an accurate multiband Stroemgren catalogue. The use of the Stroemgren index cy permits us to separate the multiple populations of M13 on the basis of their position on the red giant branch. The comparison with medium and high resolution spectroscopic analysis confirms the robustness of our selection criterion. To determine the radial distribution of stars in M13, we complemented our data set with Hubble Space Telescope observations of the cluster core, to compensate for the effect of incompleteness affecting the most crowded regions. From the analysis of the radial distributions, we do not find any significant evidence of spatial segregation. Some residuals may be present in the external regions where we observe only a small number of stars. This finding is compatible with the short dynamical time-scale of M13 and represents, to date, one of the few examples of fully spatially mixed multiple populations in a massive globular cluster.2018MNRAS.474.4438Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/474/4438CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/129/303 : Abundances of stars in M3 and M13 (Cohen+, 2005)J/A+A/505/117 : Red giants abundances in 15 globular clusters (Carretta+, 2009)J/ApJ/754/L38 : Abundances and radial velocities of M13 giants (Johnson+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/474/4438https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/474/4438http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/474/4438https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/474/4438https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/474/4438http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/474/4438GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/474/4438/table2 (Spectroscopic targets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/474/4438/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/474/4438/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/474/4438/table2?GETtext/xml+votable180.050000true250.481216436.5576820.005555555555555556Cone search capability for table J/MNRAS/474/4438/phot (Stroemgren photometry (updated file on 11/05/2020))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/474/4438/phot?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/474/4438/phot?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/474/4438/phot?GETtext/xml+votable180.050000true250.344127236.56317780.0055555555555555566/9436https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/474/4438?format=asciiOpticaldefaultJ/MNRAS/474/4438/table2Spectroscopic targetsrecnoRecord number assigned by the VizieR team.
