cds-question@unistra.frmagellanic-cloudseclipsing-binary-starsinfrared-photometryvisible-astronomyphotometryWe examined light curves of 1138 stars brighter than 18.0mag in the I band and less than a mean magnitude error of 0.1mag in the V band from the Optical Gravitational Lensing Experiment (OGLE)-III eclipsing binary catalogue, and found 90 new binary systems exhibiting apsidal motion. In this study, the samples of apsidal motion stars in the Small Magellanic Cloud (SMC) were increased by a factor of about 3.0 than previously known. In order to determine the period of the apsidal motion for the binaries, we analysed in detail both the light curves and eclipse timings using the MACHO (MAssive Compact Halo Objects) and OGLE photometric data base. For the eclipse timing diagrams of the systems, new times of minimum light were derived from the full light curve combined at intervals of one year from the survey data. The new 90 binaries have apsidal motion periods in the range of 12-897yr. An additional short-term oscillation was detected in four systems (OGLE-SMC-ECL-1634, 1947, 3035, and 4946), which most likely arises from the existence of a third body orbiting each eclipsing binary. Since the systems presented here are based on homogeneous data and have been analysed in the same way, they are suitable for further statistical analysis.2016MNRAS.460..650Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/460/650CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/134/1963 : MACHO MC eclipsing binaries r,b light curves (Faccioli+, 2007)J/AcA/54/1 : OGLE II SMC eclipsing binaries (Wyrzykowski+, 2004)J/AcA/63/323 : OGLE-III SMC eclipsing binary stars (Pawlak+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/460/650https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/460/650http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/460/650https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/460/650https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/460/650http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/460/650GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/460/650/table1 (Basic parameters of 90 binary systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/460/650/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/460/650/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/460/650/table1?GETtext/xml+votable180.050000true8.8800417-72.96766670.005555555555555556Cone search capability for table J/MNRAS/460/650/tablee1 (Apsidal motion elements and masses of the 100 known EBs in the literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/460/650/tablee1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/460/650/tablee1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/460/650/tablee1?GETtext/xml+votable180.050000true346.009173163.39684580.0055555555555555566/374 1212 1317 1753 2623 2903 2979 3313 3383 3449 3712 7089 9442 13043 13281 13705 13819 13823 13945 14130 14223 14234 14242 14246 14260 14290 14308 14331 14388 14407 14431 14434 14445 14456 14458-14459 14630 14644 14734 15195 15683 15686 15803 16096 18468 20803 20969 21432 21866 22021 22078 22249 22872 22980 23226 23994 28685 28687 29077 29866 30258 30703 31169 31838 31863 32217 32219 33091 33097-33098 33120 33293-33295 33298-33299 33304-33306 33316-33317 33328 35226 37357 37895 37899 37906 37924 38562 39130 39192 39245 39279 39804 40545 41812-41813 42071 42394 42674 42791 48013 480392.367228618189496e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/460/650?format=asciiOpticalInfrareddefaultJ/MNRAS/460/650/table1Basic parameters of 90 binary systemsrecnoRecord number assigned by the VizieR team.
