cds-question@unistra.freclipsing-binary-starsvariable-starsccd-photometryBuilding on previous work, a new search of the SuperWASP archive was carried out to identify eclipsing binary systems near the short-period limit. 143 candidate objects were detected with orbital periods between 16000 and 20000s, of which 97 are new discoveries. Period changes significant at 1{sigma} or more were detected in 74 of these objects, and in 38 the changes were significant at 3{sigma} or more. The significant period changes observed followed an approximately normal distribution with a half-width at half-maximum of ~0.1s/yr. There was no apparent relationship between period length and magnitude or direction of period change. Amongst several interesting individual objects studied, 1SWASP J093010.78+533859.5 is presented as a new doubly eclipsing quadruple system, consisting of a contact binary with a 19674.575s period and an Algol-type binary with a 112799.109s period, separated by 66.1AU, being the sixth known system of this type.2013A&A...549A..86Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A86CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/264 : Southern hemisphere ASAS Variable Stars (Pojmanski+, 2002-05)J/A+A/528/A90 : SuperWASP short period eclipsing binaries (Norton+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A86https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A86http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A86https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A86https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A86http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A86GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/549/A86/table1 (Period and period change determinations for 143 eclipsing binary candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/549/A86/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/549/A86/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/549/A86/table1?GETtext/xml+votable180.050000true0.522166738.22263890.0055555555555555566/186 420 1397 1485 1796 2311 2369 2914 3040 4795 5788 6270 6528 6628 6721 6740 7247 8450 8551 8586 8714 9263 9287 9338 9492 9582 9823 10487 10839 10855 12294 12343 12410 12558 12587 12631 12658 12660 12721 12765 12804 13079 13355 13443 13490 13543 13594 13692 13694 14993 15084 15123 16556 16666 16760 16967 17108 17487 17757 18169 18472 18751 19992 20464 20470 20508 20591 20673 22792 22828 22844 22983 23244 23718 23993 24791 24822 24829 25495 26245 26511 26566 26643 26657 26780 27605 27693 27705 28432 30106 30190 30206 31399 31675 33875 33915 33982 34272 34373 34382 35186 35715 35843 35858 36161 36700 38227 38340 38351 38378 38576 38580 39606 40291 40722 40739 40939 42803 42907 43310 43352 43686 43898 43905 44054 44098 44597 44853 45655 45870 45939 46562 46625 46725 46871 47531 47596 48020 48085 48172 48560 48689 48843https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/549/A86?format=asciiOpticaldefaultJ/A+A/549/A86/table1Period and period change determinations for 143 eclipsing binary candidatesrecnoRecord number assigned by the VizieR team.
