cds-question@unistra.frmagellanic-cloudsvariable-starsPulsation period of Cepheids should change as stars evolve through the instability strip. Rates of these changes found by other authors based on the decades-long O−C diagrams show rather good agreement with theoretical predictions. We have checked the variability on the scale of a few years on the data recently published by the Optical Gravitational Lensing Experiment (OGLE) for the Large Magellanic Cloud Cepheids and found period changes for 18% of fundamental mode and 41% of first overtone pulsators. It suggest the overtone pulsations are less stable than the fundamental ones. For stars which had the cross-references in the MACHO catalog we have checked if the period change rates derived from the OGLE and the MACHO data are consistent.2008AcA....58..313Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/58/313CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/58/163 : VI light curves of LMC classical Cepheids (Soszynski+, 2008)ftp://ftp.astrouw.edu.pl/ogle/ogle3/OIII-CVS/lmc/cep/max_time : Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/58/313https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/58/313http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/58/313https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/58/313https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/58/313http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/58/313GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/58/313/list (List of all analyzed Cepheids)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/58/313/list?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/58/313/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/58/313/list?GETtext/xml+votable180.050000true67.946-69.81933330.0055555555555555564/2068 5/8263 8268-8269 8276 8280 6/33045-33047 33049 33051 33080-33081 33084-33085 33087 33112 33124-33126 33128-33129 37416 37504 37506 37514 37536 37538https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/58/313?format=asciiOpticaldefaultJ/AcA/58/313/listList of all analyzed CepheidsrecnoRecord number assigned by the VizieR team.
