cds-question@unistra.freclipsing-binary-starsWe collect data on the masses, radii, etc., of three classes of close binary stars: low-temperature contact binaries (LTCBs), near-contact binaries (NCBs), and detached close binaries (DCBs). We restrict ourselves to systems in which (1) both components are, at least arguably, near the main sequence, (2) the periods are less than a day, and (3) there is both spectroscopic and photometric analysis leading to reasonably reliable data. We discuss the possible evolutionary connections between these three classes, emphasizing the roles played by mass loss and angular momentum loss in rapidly rotating cool stars. We describe a new mechanism, differential rotation as observed in the Sun, which can explain the remarkable efficiency of heat transport in the outer envelopes of contact binaries.2005ApJ...629.1055Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/629/1055CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/119 : Catalogue of field contact binary stars (Pribulla+, 2003)J/A+A/426/1001 : Catalog of contact binary stars (Csizmadia+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/629/1055https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/629/1055http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/629/1055https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/629/1055https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/629/1055http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/629/1055GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/629/1055/table1 (Physical parameters of well-determined low-temperature contact binaries (LTCBs))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/629/1055/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/629/1055/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/629/1055/table1?GETtext/xml+votable180.050000true29.4907537.806250.005555555555555556Cone search capability for table J/ApJ/629/1055/ncb (Near-contact binaries (table2) and detached (table3) binaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/629/1055/ncb?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/629/1055/ncb?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/629/1055/ncb?GETtext/xml+votable180.050000true32.264256940.79421640.0055555555555555566/454 739 1118 1933 2436 2452 2499 2702 2952 3042 3308 3559 4427 4698 4915 5110 5503 5836 6312 6340 6550 7262 7273 8124 8357 8579 8871 9167 9514 9578 9780 9890 9951 10301 11395 11486 11650 11984 12792 13110 13159 13181 13247 13263 13269 13618 13699 13859 14179 14528 15144 15330 16058 16186 16673 17064 18309 18856 18902 19698 19991 21969 22662 22680 22786 24232 24378 24391 24616 24982 24983 25374 25991 26368 27116 27250 27609 27770 27852 28129 28143 28432 28582 29374 30491 30565 31148 31781 31843 31944 31950 32390 33102 33323 35025 36494 36510 37890 40427 41864 41983 43455 44514 44772 44981 45448 47825https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/629/1055?format=asciiOpticaldefaultJ/ApJ/629/1055/table1Physical parameters of well-determined low-temperature contact binaries (LTCBs)recnoRecord number assigned by the VizieR team.
