cds-question@unistra.freclipsing-binary-starsgalaxy-classification-systemsCyclic period changes are a fairly common phenomenon in close binary systems and are usually explained as being caused either by the magnetic activity of one or both components or by the light travel time effect (LTTE) of a third body. We searched the orbital period changes in 182 EA-type (including the 101 Algol systems used by Hall, 1989, Space Sci. Rev., 50, 219), 43 EB-type and 53 EW-type binaries with known mass ratio and spectral type of the secondary component. We reproduced and improved the diagram in Hall according to the new collected data.2010MNRAS.405.1930Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/405/1930CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/119 : Catalogue of field contact binary stars (Pribulla+, 2003)J/MNRAS/373/435 : Angular momentum evolution of Algol binaries (Ibanoglu+ 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/405/1930https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/405/1930http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/405/1930https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/405/1930https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/405/1930http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/405/1930GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/405/1930/EBs (Period changes of semi-detached and detached Algol-type binaries (table1), EB-type (table2) and EW-type (table3) binaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/405/1930/EBs?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/405/1930/EBs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/405/1930/EBs?GETtext/xml+votable180.050000true348.344583346.14750.0055555555555555566/14 454 901 1020 1072 1163 1213 1293 1299 1302 1339 1397 1427 1429 1504 1621 1628 1704 1726 1933 2119 2459 2499 2908 2936 3042 3060 3113 3250 3283 3384 3628 3630 3636 3668 3830 3841 3849 3873 3956 4028 4254 4279 4298 4372 4427 4589 4696 4698 5110 5602 5627 5638 5895 6340 6663 6783 6898 7262 7281 7637 7902 8076 8124 9044 9074 9144 9415 9566 9570 9578 9866 10045 10169 10305 10336 10401 10474 10775 11290 11486 11543 11657 11984 12145 12276 12325 12372 12430 12493 12577 12760 12839 12879 12924 12949 13032 13045 13110 13247 13535 13618 13699 13794 13808 13822 13933 13935 13947 14041 14184 14256 14259 14307 14331 14368 14381 14391 14423 14537 14607 14619 14630 14692 14702 14739 14798 14801 14808 14855 14895 14933 15036 15137 15189 15327 15654 15662 15669 15711 15713 15726 15809 16145 16186 16226 16256 16274 16673 17759 18309 18889 19346 19598 19698 19991 20271 20422 20735 21532 21536 21598 21622 21643 21731-21732 21891 21952 21962 21969 22037 22114 22287 22514 22625 22680 22753 23086 23183 23300 23483 23744 23917 24004 24232 24238 24256 24333 24415 24948 24982 25100 25991 26020 26112 27116 27250 27481 27491 27609 27770 27852 28129 28143 28149 28738 28799 28809 28830 29374 29505 29531 29836 29880 30281 30343 30491 30551 30617 31148 31169 31227 31432 31781 31863 31881 31994 32001 32092 32141 32193 32307 32521 32645 32694 32720 33027 33317 34914 36484 36494 36805 37212 37890 37897 37910 38016 38023 38533 39201 40030 40131 40279 40427 40496 40887 40891 40900 41715 41726 41864 42877 43129 43227 44514 44720 44795 44981 44993 46179 47757 48833 48862 48874 48974https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/405/1930?format=asciiOpticaldefaultJ/MNRAS/405/1930/EBsPeriod changes of semi-detached and detached Algol-type binaries (table1), EB-type (table2) and EW-type (table3) binariesrecnoRecord number assigned by the VizieR team.
