cds-question@unistra.frmilky-way-galaxyopen-star-clustersvariable-starsvisible-astronomyWe have performed a critical evaluation of the membership status of all variable stars in globular clusters recorded in the Catalogue of Variable Stars in Globular Clusters (CVSGC) curated by Christine Clement. To this end, we employed the systematic and bulky membership analysis performed by E. Vasiliev and H. Baumgardt based on the proper motions and parallaxes given in Gaia-EDR3. We found numerous variables in the CVSGC which are in fact field stars, which is particularly the case for globular clusters located in the Galactic bulge. Using the newly acquired list of reliable cluster members we examine the Oosterhoff dichotomy present among the Milky Way (MW) globular clusters using their RR Lyrae stars content. We confirm the presence of the Oosterhoff gap, separating both Oosterhoff groups. The Oosterhoff gap is mostly populated by globular clusters associated with MW dwarf galaxies and globular clusters with a low number of fundamental mode RR Lyrae variables. Several of the clusters in the Oosterhoff gap were previously linked to past merger events (e.g. Kraken/Heracles).2024MNRAS.534.3654Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/534/3654CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/150 : Updated catalog of variable stars in globular clustersJ/MNRAS/505/5978 : Gaia EDR3 view on Galactic globular clustershttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/534/3654https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/534/3654http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/534/3654https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/534/3654https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/534/3654http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/534/3654GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/534/3654/clusters (Studied clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/534/3654/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/534/3654/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/534/3654/clusters?GETtext/xml+votable180.050000true272.4020833-20.77886110.005555555555555556Cone search capability for table J/MNRAS/534/3654/members (Variable stars and their cluster membership probabilities (table 2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/534/3654/members?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/534/3654/members?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/534/3654/members?GETtext/xml+votable180.050000true272.3935-20.79688890.0055555555555555565/10806 6/1133 6389 9436 9666 10008 10321 10336-10338 12405 12425 12531 12943 14489 16647 17121 17979 18673 19091 19100 19979 20001 21017 24843 25367 25873 27237 27975 27981 27984 27986 27992 28067 28577 28705 28717 28741 28751 28762 28768-28770 28778 28815 28838 28867-28868 28877 28882 28888-28889 28899 28905 28962-28963 28966-28970 28972-28974 29090 29184-29185 29187 29195 29202 29216 29218 29222 29231 29233 29248 29291 29294 29318 29377 29626 29636-29637 29870 30199 30321 30323 30329 30378 30769 30995 30998 31019 31043 31095 31115 31128 31396 31398 31416-31417 31778 32080 32083 33321 33323-33324 33330 33634-33635 34242-34243 36334 36971 37294 38465-38468 39642 41011 41257 41260 41304-41305 41507 41513 41522 41847 41852 42076 42275 42278 42314 42320 42336 42361 42700 42761 42841 42955 42958 42977 42990-42991 43125 43193 43228 43230 43249 44086 44220 44427 47125 47168 47278 47620 47755 47777 47825 47828 47865-47866 47868 47903 47935 47971 47977 48035 48041 48434 48444 48698 48952https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/534/3654?format=asciiOpticaldefaultJ/MNRAS/534/3654/clustersStudied clustersrecnoRecord number assigned by the VizieR team.
