cds-question@unistra.frvariable-starseclipsing-binary-starsWe have created a catalogue of variable stars found from a search of the publicly available K2 mission data from Campaigns 1 and 0. This catalogue provides the identifiers of 8395 variable stars, including 199 candidate eclipsing binaries with periods up to 60d and 3871 periodic or quasi-periodic objects, with periods up to 20d for Campaign 1 and 15d for Campaign 0. Lightcurves are extracted and detrended from the available data. These are searched using a combination of algorithmic and human classification, leading to a classifier for each object as an eclipsing binary, sinusoidal periodic, quasi periodic, or aperiodic variable. The source of the variability is not identified, but could arise in the non-eclipsing binary cases from pulsation or stellar activity. Each object is cross-matched against variable star related guest observer proposals to the K2 mission, which specifies the variable type in some cases. The detrended lightcurves are also compared to lightcurves currently publicly available. The resulting catalogue is made available online at http://deneb.astro.warwick.ac.uk/phrlbj/k2varcat/, and gives the ID, type, period, semi-amplitude and range of the variation seen. We also make available the detrended lightcurves for each object.2015A&A...579A..19Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/579/A19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://deneb.astro.warwick.ac.uk/phrlbj/k2varcat/ : K2VarCat home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/579/A19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/579/A19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/579/A19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/579/A19https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/579/A19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/579/A19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/579/A19/table3 (K2 Variable Catalogue, version 2015-02-12)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/579/A19/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/579/A19/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/579/A19/table3?GETtext/xml+votable180.050000true176.7105167-5.97357220.0055555555555555564/1496 1499 1502 1686-1687 1693 1730 5/5962-5966 5977 5979 5988 5990-5993 5995 6002-6003 6006-6007 6012 6014-6015 6081 6084-6085 6096-6098 6394 6398 6725-6727 6733 6735-6736 6738-6739 6742-6743 6757 6768-6769 6771 6780 6915 6926 6944-6946 6952 6/23679 23765 23774-23775 23797 23799 23835 23838-23839 23846-23847 23868 23870 23905 23907 23913 23922 23956 23958-23959 23976-23977 23979 24001-24004 24006-24007 24019 24022-24023 24052 24054 24332-24333 24335 24344-24345 24348-24349 24351 24373 24396-24397 24400-24402 24404 24416 25533-25535 25570-25571 25580-25582 25586-25587 25590 25596-25598 26899 26928-26929 26931 26939 26948 26961 26963-26964 26966 27025 27037 27080-27081 27083 27108-27109 27111 27124-27125 27651-27652 27654-27655 27657-27659 27672 27674 27698 27788-27790 27792 27812https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/579/A19?format=asciidefaultJ/A+A/579/A19/table3K2 Variable Catalogue, version 2015-02-12recnoRecord number assigned by the VizieR team.
