cds-question@unistra.frmultiple-starsstellar-massesinfrared-photometryvisible-astronomyphotometryeffective-temperatureHigh precision CCD observations of six totally eclipsing contact binaries were presented and analyzed. It is found that only one target is an A-type contact binary (V429Cam), while the others are W-type contact ones. By analyzing the times of light minima, we discovered that two of them exhibit secular period increase while three manifest long-term period decrease. For V1033Her, a cyclic variation superimposed on the long-term increase was discovered. By comparing the Gaia distances with those calculated by the absolute parameters of 173 contact binaries, we found that the Gaia distance can be applied to estimate the absolute parameters for most contact binaries. The absolute parameters of our six targets were estimated using their Gaia distances. The evolutionary status of contact binaries was studied, and we found that the A- and W-subtype contact binaries may have different formation channels. The relationship between the spectroscopic and photometric mass ratios for 101 contact binaries was presented. It was discovered that the photometric mass ratios are in good agreement with the spectroscopic ones for almost all of the totally eclipsing systems, which is corresponding to the results derived by Pribulla et al. and Terrell & Wilson.2021AJ....162...13Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/162/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2017)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)II/366 : ASAS-SN catalog of variable stars (Jayasinghe+, 2018-2020)J/A+A/519/A78 : BVR light curves of KR Com (Zasche+, 2010)J/A+A/525/A66 : 4 close binaries BVR light curves (Djurasevic+, 2011)J/MNRAS/412/1787 : Physical parameters of 62 eclipsing binaries (Deb+, 2011)J/AJ/148/126 : Light curves of four overcontact binaries (Caliskan+, 2014)J/ApJ/788/48 : X-ray through NIR photometry of NGC 2617 (Shappee+, 2014)J/AJ/154/260 : 3 short-period eclipsing binaries BVRI photometry (Pi+, 2017)J/other/RMxAA/53.235 : Photometry of 6 deep-contact W UMa (Kjurkchieva+, 2017)J/AJ/157/111 : Study of three early-type contact twin binaries (Yang+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/162/13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/162/13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/162/13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/162/13https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/162/13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/162/13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/162/13/table1 (Information of the six targets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/162/13/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/162/13/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/162/13/table1?GETtext/xml+votable180.050000true93.277541776.49691670.005555555555555556Cone search capability for table J/AJ/162/13/table7 (The 173 contact binaries with spectroscopic and photometric observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/162/13/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/162/13/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/162/13/table7?GETtext/xml+votable180.050000true347.883691936.89308530.0055555555555555566/147 263 400 454 739 761 1118 1314 1441 1691 1773 1933 2436 2452 2483 2499 2702 2952 3042 3201 3559 3707 4012 4425 4427 4698 4703 5110 5212 5414 5427 5503 5656 5836 6312 6354 7262 7934 8030 8040 8100 8141 8357 8419 8579 8656 8716 8871 9167 9292 9354 9415 9514 9578 9625 9780 9890 9922 9951 10002 10183 10601 10706 10775 10923 11162 11181 11278 11290 11337 11395 11486 11576 11650 12792 12885 13159 13181 13437 13618 13699 13859 14087 14528 14619 14698 15329 15850 16058 16137 16186 17310 17508 18234 18902 19075 19448 19650 19698 19914 19998 20034 20270 21749 21969 22208 22662 22680 22696 22786 22929 24232 24378 24391 24616 24983 25408 25835 26097 26391 26495 26850 27017 27116 27250 27481 27603 27639 27770 27852 27984 28129 28143 28296 28432 28809 29671 30491 30565 31148 31546 31604 31781 31812 31843 31886 31944 31950 32110 32307 32713 32999 33102 33323 33591 34611 35025 35422 36494 36650 36805 37890 37910 39035 39933 40427 41705 41864 41983 42060 43455 44514 44772 44981 45287 46084 47243 47825https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/162/13?format=asciiOpticalInfrareddefaultJ/AJ/162/13/table1Information of the six targetsOCInteractive Plotmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
