cds-question@unistra.frvariable-starsgiant-starsphotometryWe have analyzed two epochs of Hubble Space Telescope Wide Field Planetary Camera 2 observations of the Ursa Minor dwarf spheroidal galaxy using the HSTphot photometric reduction package. We report the detection of nine faint (M_V_>~0.0mag) red giant variable stars that exhibit low-amplitude brightness fluctuations on 10 minute timescales with amplitudes ranging from 36 to 130mmag.2004ApJ...617L..41Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/617/L41CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/90/2221 : UMi dwarf galaxy BV photometry (Olszewski+, 1985)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/617/L41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/617/L41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/617/L41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/617/L41https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/617/L41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/617/L41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/617/L41/table1Photometry of the RGB variable candidatesrecnoRecord number assigned by the VizieR team.
