cds-question@unistra.frgalaxiesphotometryccd-photometrycarbon-starsWe used the CFH12K wide field camera to survey the carbon star population of the Wolf-Lundmark-Melotte system using the CN-TiO technique. 149 C stars are identified with a mean <I>=20.28, corresponding to <M_I_>=-4.65, a mean luminosity similar to what we found in other irregular galaxies. Star counts in and around the main body of WLM reveal that its stellar distribution is quite elliptical ({epsilon}=0.58) with major and minor axes of 26' and 11'. Comparison of the density profile of C stars and old red giants shows that their scale lengths differ by only 15% pointing to mixed populations. Wolf-Lundmark-Melotte is found to be unique among dwarf irregular galaxies by having essentially a handful of early-type AGB M stars thus leading to an extreme C/M ratio.2004A&A...416..111Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/416/111CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/119/2780 : C stars in IC 1613 (Albert+, 2000)J/AJ/120/1801 : C stars in Pegasus, DDO 210 and Tucana (Battinelli+, 2000)J/AJ/123/832 : C star population in NGC 6822 (Letarte+, 2002)J/AJ/125/1298 : C star population in outer disk of M31 (Battinelli+, 2003)J/A+A/410/795 : Photometry of NGC 3109 carbon stars (Demers+, 2003)J/AJ/125/3037 : RI photometry of NGC 205 carbon stars (Demers+, 2003)J/A+A/417/479 : RI photometry of NGC 185 carbon stars (Battinelli+, 2004)J/A+A/418/33 : RI photometry of C stars in NGC 147 (Battinelli+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/416/111https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/416/111http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/416/111https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/416/111https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/416/111http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/416/111GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/416/111/table2 (Positions and photometry of 149 C stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/416/111/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/416/111/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/416/111/table2?GETtext/xml+votable180.050000true0.4055833-15.43880560.0055555555555555566/17165https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/416/111?format=asciiOpticaldefaultJ/A+A/416/111/table2Positions and photometry of 149 C starsrecnoRecord number assigned by the VizieR team.
