cds-question@unistra.frmultiple-starsA catalogue of light curve solutions of contact binary stars has been compiled. It contains the results of 159 light curve solutions. Properties of contact binary stars were studied by using the catalogue data. As it is well known since Lucy's (1968ApJ...151.1123L, 1968ApJ...153..877L) and Mochnacki's (1981ApJ...245..650M) works, primary components transfer their own energy to the secondary star via the common envelope around the two stars. This transfer was parameterized by a transfer parameter (ratio of the observed and intrinsic luminosities of the primary star). We proved that this transfer parameter is a simple function of the mass and luminosity ratio. This newly found relation is valid for all systems except H type systems which have a different relation. We introduced a new type of contact binary stars: H subtype systems which have a large mass ratio (q>0.72). These systems show highly different behaviour on the luminosity ratio - transfer parameter diagram from other systems and according to our results the energy transfer rate is less efficient in them than in other type of contact binary stars.2004A&A...426.1001Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/426/1001CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/250 : Combined General Catalogue of Variable Stars (Samus+ 2004)V/119 : Field contact binary stars catalog (Pribulla+, 2003)J/AcA/51/259 : Contact binaries in OGLE-I database (Szymanski+, 2001)J/PASP/108/332 : Photometric analysis of contact binaries (Lapasset+ 1996)J/A+A/311/523 : Photometry of W UMa (Maceroni+, 1996)J/A+A/327/1017 : GO Cygni system (Rovithis-Livaniou+ 1997)J/A+A/355/171 : TZ Boo + Y Sex orbital periods (Qian+, 2000)J/A+A/395/587 : GR Tau BV light curves (Zhang+, 2002)J/A+A/403/637 : V and R light curves of GSC 3822-1056 (Csizmadia+, 2003)J/A+A/417/745 : V861 Her V(RI)C differential photometry (Csizmadia+ 2004)J/A+AS/106/373 : AB And UBV photometry (Demicran+, 1994)J/A+AS/122/515 : HL Aur light curves and minima (Zhang+ 1997)J/A+AS/136/139 : VB light curves of YY Eri (Yang+, 1999)J/AJ/109/359 : H235 in NGC 752 (Milone+ 1995)J/AJ/110/2400 : BVI photometry of V728 Her (Nelson+ 1995)J/AJ/116/2549 : HW Per UBV differential photometry (Samec+, 1998)J/PASP/108/338 : UBV obs. of the contact binary BF Pav (Gonzalez+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/426/1001https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/426/1001http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/426/1001https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/426/1001https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/426/1001http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/426/1001GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/426/1001/table2a (Catalogue of the light curve solutions of W UMA stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/426/1001/table2a?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/426/1001/table2a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/426/1001/table2a?GETtext/xml+votable180.050000true347.883708336.89308330.005555555555555556Cone search capability for table J/A+A/426/1001/table3 (Results of light curve solutions made by the BINSYN code)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/426/1001/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/426/1001/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/426/1001/table3?GETtext/xml+votable180.050000true160.138272513.5669055560.0055555555555555566/454 474 739 1291 1647 1679 1708 1933 2436 2499 2702 2806 2907 2952 3042 3308 3722 4020 4078 4146 4254 4298 4425 4427 4698 5110 5503 5602 5656 5836 6075 6375 7262 8040 8357 8579 8656 8871 9167 9415 9578 9608 9615 9780 9951 10326 10648 10775 11100 11117 11181 11290 11486 11650 12792 12885 13123 13181 13306 13618 13699 13818 13859 14155 14245 14268 14537 14619 14666 14692 14719 14723 15134 16058 16186 18902 19448 19698 20993 21969 22241 22662 22680 22696 22786 22902 24232 24377 24391 24616 24628 25374 26380 27116 27250 27481 27603 27770 28129 28143 28149 28296 28432 28450 28582 28679 28809 28830 29374 29880 30220 30491 30565 31148 31781 31843 31944 32004 32307 32390 32787 32838 33102 33323 34371 35025 35115 35208 35422 36494 36517 37890 37897 37910 39220 39245 39274 39933 40030 40294 41514 41705 41726 41864 41983 42060 43355 43379 43455 45282 45287 45597 46058 47030 47131 47825 48023https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/426/1001?format=asciiOpticaldefaultJ/A+A/426/1001/table2aCatalogue of the light curve solutions of W UMA starsrecnoRecord number assigned by the VizieR team.
