cds-question@unistra.frgalaxiesvariable-starshst-photometryWe present HST/ACS observations of RR Lyrae variable stars in six ultra-deep fields of the Andromeda galaxy (M31), including parts of the halo, disk, and giant stellar stream. Past work on the RR Lyrae stars in M31 has focused on various aspects of the stellar populations that make up the galaxy's halo, including their distances and metallicities. This study builds upon this previous work by increasing the spatial coverage (something that has been lacking in previous studies) and by searching for these variable stars in constituents of the galaxy not yet explored.2011AJ....141..171Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/171CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/138/184 : RR Lyrae in 2 fields in M31 spheroid (Sarajedini+, 20J/A+A/402/113 : (RI)c photometry of variables in M31 (Joshi+, 2003)J/AJ/127/2738 : ACS VI photometry of M31 halo RR Lyrea (Brown+, 2004)J/ApJS/184/152 : Deep optical photometry in M31 (Brown+, 2009)J/ApJ/708/817 : RR Lyrae variables in M32 and M31 (Fiorentino+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/171https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/171http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/171https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/171https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/171http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/171GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/141/171/stars (*Properties of RR Lyrae and Cepheid stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/171/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/171/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/171/stars?GETtext/xml+votable180.050000true12.312333342.73594440.005555555555555556Cone search capability for table J/AJ/141/171/table9 (Properties of RR Lyrae stars found in the halo11 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/171/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/171/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/171/table9?GETtext/xml+votable180.050000true11.54962540.71252780.0055555555555555566/2620 2621 2623 2658 26672.0401237512456292e-19 3.9057996558789745e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/141/171?format=asciiOpticaldefaultJ/AJ/141/171/stars*Properties of RR Lyrae and Cepheid starsrecnoRecord number assigned by the VizieR team.
