cds-question@unistra.frgalaxiesphotometryinfrared-photometryvisible-astronomybroad-band-photometryWe present results from ground-based optical imaging of a low-mass dwarf galaxy discovered by the ALFALFA 21cm HI survey. Broadband (BVR) data obtained with the WIYN 3.5m telescope at Kitt Peak National Observatory (KPNO) are used to construct color-magnitude diagrams of the galaxy's stellar population down to V_o_~25. We also use narrowband H{alpha} imaging from the KPNO 2.1m telescope to identify a HII region in the galaxy. We use these data to constrain the distance to the galaxy to be between 1.5 and 2.0Mpc. This places Leo P within the Local Volume but beyond the Local Group. Its properties are extreme: it is the lowest-mass system known that contains significant amounts of gas and is currently forming stars.2013AJ....145..149Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/149CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/144/4 : Properties of dwarf galaxies in the LG (McConnachie+, 2012)J/AJ/142/170 : ALFALFA survey: the {alpha}.40 HI sce catalog (Haynes+, 2011)J/ApJ/704/898 : Photometry of the Hercules dwarf galaxy (Sand+, 2009)J/AJ/133/715 : Dwarf galaxies of the Local Group (Whiting+, 2007)J/MNRAS/354/708 : Leo I VI photometry (Bellazzini+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/145/149https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/145/149http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/145/149https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/145/149https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/145/149http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/145/149GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/145/149/table1 (WIYN broadband photometry of resolved stars in Leo P)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/145/149/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/145/149/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/145/149/table1?GETtext/xml+votable180.050000true155.43791718.0881390.0055555555555555566/4433https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/145/149?format=asciiOpticalInfrareddefaultJ/AJ/145/149/table1WIYN broadband photometry of resolved stars in Leo PrecnoRecord number assigned by the VizieR team.
