cds-question@unistra.frgalaxiesvariable-starsphotometryWe have conducted a long-term V-band photometric monitoring of M33 on 95 nights during four observing seasons (2000-2003). A total number of 6418 light curves of bright objects in the range of 14-21mag have been obtained. All measurements are publicly available. A total of 127 new variables were detected, of which 28 are periodic. 10 previously known non-periodic variables were identified as periodic, three of which are Cepheids, and another previously known periodic variable was identified as an eclipsing binary. Our derived periods range from 2.11 to almost 300d. For 50 variables we have combined our observations with those of the DIRECT project, obtaining light curves of up to 500 measurements, with a time-span of ~7yr. We have detected a few interesting variables, including a 99.3d periodic variable with a 0.04mag amplitude, at the position of supernova remnant (SNR) 19.2006MNRAS.370.1429Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/370/1429CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/121/870 : BVI photometry of Variables in M33 (Macri+, 2001)J/AJ/121/861 : BVI photometry of central part of M33 (Macri+, 2001)J/AJ/121/2032 : DIRECT variables in M33A field (Mochejska+, 2001)J/AJ/122/2477 : DIRECT variables in M33B field (Mochejska+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/370/1429https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/370/1429http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/370/1429https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/370/1429https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/370/1429http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/370/1429GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/370/1429/table11 (List of identified variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/370/1429/table11?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/370/1429/table11?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/370/1429/table11?GETtext/xml+votable180.050000true23.484416730.56633330.0055555555555555566/2154-2155https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/370/1429?format=asciiOpticaldefaultJ/MNRAS/370/1429/table11List of identified variablesrecnoRecord number assigned by the VizieR team.
