cds-question@unistra.frglobular-star-clustersultraviolet-photometryWe present a far-ultraviolet FUV study of the globular cluster M30 (NGC 7099). The images were obtained using the Advanced Camera for Surveys (ACS/SBC, F150LP, FUV) and the Wide Field Planetary Camera 2 (WFPC2, F300W, UV) which were both on board the Hubble Space Telescope (HST). The FUV-UV colour-magnitude diagram (CMD) shows a main sequence (MS) turnoff at FUV~22mag and FUV-UV~3mag. The MS extends 4 mag below the turnoff, and a prominent horizontal branch (HB) and blue straggler (BS) sequence can be seen. A total of 1218 MS stars, 185 red giant branch stars, 47 BS stars and 41 HB stars are identified, along with 78 sources blueward of the MS which consist of white dwarfs (WDs) and objects in the gap between the WDs and the MS that include potential cataclysmic variable (CV) candidates. The radial distribution of the BS population is concentrated towards the cluster centre, indicating that mass segregation has occurred. The blue and red sub-populations of the double BS sequence appear mixed in the ultraviolet CMD, and no significant central concentration of CV candidates is seen in this cluster.2022MNRAS.511.3785Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/511/3785CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)J/AJ/116/1757 : M30 UBV photometry (Guhathakurta+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/511/3785https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/511/3785http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/511/3785https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/511/3785https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/511/3785http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/511/3785GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/511/3785/catalog (M30 FUV and UV catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/511/3785/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/511/3785/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/511/3785/catalog?GETtext/xml+votable180.050000true325.08723-23.182140.0055555555555555566/484343.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/511/3785?format=asciiUVdefaultJ/MNRAS/511/3785/catalogM30 FUV and UV cataloguerecnoRecord number assigned by the VizieR team.
