Their periods are in the range of 0.26-0.43d. The light curve solutions revealed that the components of each target are almost equal in temperature. The stellar components are of G and K spectral types and undergo total eclipses. All targets have deep-contact configurations with fillout factor f>=0.5. NSVS 6859986 has one o f the biggest value determined until now, f=0.84. We studied the empirical dependencies of fillout factor on the stellar parameters (temperature, period, mass ratio, relative component radii, and luminosity ratio) for a sample of around thirty stars. They are consistent with the theoretical predictions but there are deviations from the common trends.2017RMxAA..53..235Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RMxAA/53.235CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/311/523 : Photometry of W UMa (Maceroni+, 1996)J/A+A/336/920 : HD 163151: a new W UMa type system (Rodriguez+ 1998)J/MNRAS/357/497 : Kinematics of W UMa-type binaries (Bilir+, 2005)J/AJ/143/99 : Photometry of W UMa eclipsing binaries (Terrell+, 2012)J/AJ/144/149 : CCD photometry of W UMa type TY Boo (Christopoulou+, 2012)J/AJ/146/70 : Spectroscopy of W UMa-type binary stars (Rucinski+, 2013)J/MNRAS/430/2029 : Initial masses of W UMa type contact binaries (Yildiz+ 2013)J/MNRAS/437/185 : W UMa-type contact binaries ages and masses (Yildiz, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RMxAA/53.235https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RMxAA/53.235http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RMxAA/53.235https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RMxAA/53.235https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RMxAA/53.235http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RMxAA/53.235GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RMxAA/53.235/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RMxAA/53.235/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RMxAA/53.235/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RMxAA/53.235/stars?GETtext/xml+votable180.050000true109.270541777.17391670.0055555555555555566/1317 6531 8100 11377 13457 23930https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RMxAA/53.235?format=asciiOpticaldefaultJ/other/RMxAA/53.235/starsList of studied starsSimbadNameSimbad column added by the CDSmeta.idcharPerPeriod (from table 1)dtime.perioddoublerecnoRecord number assigned by the VizieR team.
