cds-question@unistra.frmagellanic-cloudsinfrared-photometryvariable-starsWe have obtained deep infrared J- and K-band observations of nine 4.9x4.9arcmin fields in the Small Magellanic Cloud (SMC) with the ESO New Technology Telescope equipped with the SOFI infrared camera. In these fields, 34 RR Lyrae stars cataloged by the OGLE collaboration were identified. Using different theoretical and empirical calibrations of the infrared period-luminosity-metallicity relation, we find consistent SMC distance moduli, and find a best true distance modulus to the SMC of 18.97+/-0.03 (statistical) +/-0.12 (systematic) mag, which agrees well with most independent distance determinations to this galaxy, and puts the SMC 0.39mag more distant than the Large Magellanic Cloud for which our group has recently derived, from the same technique, a distance of 18.58mag.2009AJ....138.1661Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/138/1661CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/60/165 : VI light curves of SMC RR Lyrae (Soszynski+, 2010)J/AJ/135/1993 : JHK magnitudes of Sculptor RR Lyrae (Pietrzynski+, 2008)J/MNRAS/353/705 : OGLE Variables in Magellanic Clouds (Ita+, 2004)J/AcA/49/437 : BVI photometry of OGLE SMC Cepheids (Udalski+, 1999)J/AcA/48/113 : OGLE RR Lyrae VI photometry (Udalski, 1998)J/AcA/48/147 : OGLE SMC BVI photometry (Udalski+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/138/1661https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/138/1661http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/138/1661https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/138/1661https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/138/1661http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/138/1661GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/138/1661/table1 (Observational information on the target fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/138/1661/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/138/1661/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/138/1661/table1?GETtext/xml+votable180.050000true10.49-73.0750.005555555555555556Cone search capability for table J/AJ/138/1661/table3 (Individual Js- and Ks-band observations of RR Lyrae stars in SMC fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/138/1661/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/138/1661/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/138/1661/table3?GETtext/xml+votable180.050000true10.5486667-73.05811110.0055555555555555566/33294 33295 33306 33316 333177.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/138/1661?format=asciiInfrareddefaultJ/AJ/138/1661/table4Averaged and extinction-corrected magnitudes of observed RR Lyrae starsType[ab/c ] RR Lyrae typemeta.notecharrecnoRecord number assigned by the VizieR team.
