cds-question@unistra.frgalaxiesvisible-astronomybroad-band-photometryradial-velocityA new large-area Washington M, T2+DDO51 filter survey of more than 10deg^2^ around the Carina dSph galaxy reveals a spectroscopically confirmed power-law radial density break population of Carina giant stars extending several degrees beyond the central King profile. Magellan telescope MIKE spectroscopy establishes the existence of Carina stars to at least 4.5 times its central King limiting radius, rlim, and primarily along Carina's major axis. To keep these stars bound to the dSph would require a global Carina mass-to-light ratio of M/L>=6300(M/L)_{sun}}. The MIKE velocities, supplemented with ~950 additional Carina field velocities from archived VLT+GIRAFFE spectra with r<~rlim, demonstrate a nearly constant Carina velocity dispersion (sigma_v_) to just beyond r=rlim and both a rising and a velocity shear at still larger radii. Together, the observational evidence suggests that the discovered extended Carina population represents tidal debris from the dSph.2006ApJ...649..201Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/649/201CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/114/1458 : The Carina Dwarf (Mighell 1997)J/AJ/115/1856 : Dwarf Cepheids in Carina (Mateo+, 1998)J/AJ/125/1352 : Ursa Minor dSph M,T2, DDO51 photometry (Palma+, 2003)J/AJ/130/2677 : Stars in the Carina dSph galaxy field (Majewski+, 2005)J/AJ/131/895 : Stars in the Carina dwarf spheroidal galaxy (Koch+, 2006)J/ApJ/663/960 : Radial velocities of Leo I stars (Sohn+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/649/201https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/649/201http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/649/201https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/649/201https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/649/201http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/649/201GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/649/201/data (Velicities and photometry of stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/649/201/data?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/649/201/data?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/649/201/data?GETtext/xml+votable180.050000true97.8464583-50.80486110.0055555555555555565/9773 9774 6/39070 39071 39089 39091 39100 39101 39102https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/649/201?format=asciiOpticaldefaultJ/ApJ/649/201/dataVelicities and photometry of stars observedrecnoRecord number assigned by the VizieR team.
