cds-question@unistra.frvariable-starsphotometryWe present a search for variable stars in the Fornax dwarf galaxy covering an area of half a square degree. We have ~30 epochs of VI data. We found and determined periods for more than 500 RR Lyrae, 17 anomalous Cepheids, and six Population II Cepheids. In addition we have 85 candidate long-period variables, the majority of which were previously unknown. We estimate that the average metal abundance of RR Lyrae stars is [Fe/H]~=-1.6dex.2002AJ....123..840Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/123/840CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/123/840https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/123/840http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/123/840https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/123/840https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/123/840http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/123/840GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/123/840/table2 (RR Lyrae variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/840/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/840/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/840/table2?GETtext/xml+votable180.050000true39.86-34.6741670.005555555555555556Cone search capability for table J/AJ/123/840/table3 (Anomalous Cepheids and Population II Cepheids)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/840/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/840/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/840/table3?GETtext/xml+votable180.050000true39.51625-34.6394440.005555555555555556Cone search capability for table J/AJ/123/840/table4 (Candidate and known Long Period Variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/840/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/840/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/840/table4?GETtext/xml+votable180.050000true39.5-34.7394440.0055555555555555566/35882-35883 35968-35969https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/123/840?format=asciiOpticaldefaultJ/AJ/123/840/table1Journal of observationsrecnoRecord number assigned by the VizieR team.
