cds-question@unistra.freclipsing-binary-starssolar-system-planetsphotometryWe present light curves and periods of 53 candidates for short period eclipsing binary stars identified by SuperWASP. These include 48 newly identified objects with periods <2x10^4^s (~0.23d), as well as the shortest period binary known with main sequence components (GSC2314-0530 = 1SWASP J022050.85+332047.6) and four other previously known W UMa stars (although the previously reported periods for two of these four are shown to be incorrect). The period distribution of main sequence contact binaries shows a sharp cut-off at a lower limit of around 0.22d, but until now, very few systems were known close to this limit. These new candidates will therefore be important for understanding the evolution of low mass stars and to allow investigation of the cause of the period cut-off.2011A&A...528A..90Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/528/A90CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/467/785 : SuperWASP/ROSAT periodic variable stars (Norton+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/528/A90https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/528/A90http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/528/A90https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/528/A90https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/528/A90http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/528/A90GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/528/A90/table1 (Short period eclipsing binaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/528/A90/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/528/A90/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/528/A90/table1?GETtext/xml+votable180.050000true80.15353.067250.0055555555555555566/186 1397 1796 2311 3040 4795 5811 6628 6671 7247 8551 9492 9585 12294 12343 12587 12721 13355 13443 13692 14993 15084 16556 16967 18169 19469 22792 22844 22983 23244 24791 24822 25495 26566 27705 31263 31399 31923 32300 33982 34382 35858 36161 38227 38340 38580 42907 43905 44597 45010 46625 46871 48680https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/528/A90?format=asciiOpticaldefaultJ/A+A/528/A90/table1Short period eclipsing binariesrecnoRecord number assigned by the VizieR team.
