cds-question@unistra.freclipsing-binary-starsx-ray-sourcesContact binary stars are common variable stars that are all believed to emit relatively large fluxes of X-rays. In this work we combine a large new sample of contact binary stars derived from the ROTSE-I telescope (Cat. <J/AJ/131/621>) with X-ray data from the ROSAT All Sky Survey (RASS, Cat. <IX/10>) to estimate the X-ray volume emissivity of contact binary stars in the Galaxy. We obtained X-ray fluxes for 140 contact binaries from the RASS, as well as two additional stars observed by the XMM-Newton observatory.2006AJ....131..633Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/633CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)J/AJ/119/1901 : ROTSE all-sky surveys for variable stars (Akerlof+, 2000)J/AJ/131/621 : A catalog of 1022 bright contact binary stars (Gettel+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/633https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/633http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/633https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/633https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/633http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/633GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/633/table1 (Properties of RASS objects in the contact binary catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/633/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/633/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/633/table1?GETtext/xml+votable180.050000true328.64-10.0360.0055555555555555566/49 263 739 990 994 1314 1933 2483 2990 3444 3559 3722 4012 4056 4105 4509 4698 5110 5122 5262 5625 6212 6230 6685 6742 7063 7326 8100 8228 8663 8716 8779 8871 9107 9449 9481 9567 9576 9625 9647 9714 9951 9955 10168 10335 10666 10809 11256 11278 11305 11312 11395 11466 11495 11600 11624 11640 11644 11650 11695 11761 11765 11889 11955 12111 12113 12223 12273 12494 12795 13368 13488 13511 13595 13617 14666 15012 15053 15218 15284 15488 15544 15604 15754 15835 15952 16058 16093 16243 16781 17290 18278 18595 18708 18717 19075 19230 19528 19934 20554 20894 21425 22987 23015 23243 23974 24116 25330 26195 26380 27177 27699 28018 28149 30270 30549 31812 31843 32179 32255 32371 32507 32649 32722 32738 35533 36149 36494 36537 36805 39861 40173 40429 40430 40715 40938 49102 49127https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/633?format=asciiX-raydefaultJ/AJ/131/633/table1Properties of RASS objects in the contact binary catalogrecnoRecord number assigned by the VizieR team.
