cds-question@unistra.frvariable-starsccd-photometryinfrared-photometryvisible-astronomybroad-band-photometrykron-cousins-photometryUsing extended multicolour CCD photometry of the triple-mode radial pulsator V823 Cas we studied the properties of the coupling frequencies invoked by nonlinear processes. Our results support that a resonance connection affects the mode coupling behaviour. The P1/P0 period ratio of V823 Cas has an "out of range" value if compared with the period ratios of the known double mode pulsators, while the P2/P1 period ratio is normal. The periods and period ratios cannot be consistently interpreted without conflict with pulsation and/or evolution models. We describe this failure with the suggestion that at present, the periods of V823 Cas are in a transient, resonance affected state, thus do not reflect the true parameters of the object. The anomalous period change behaviour of the fundamental and second overtone modes supports this idea. We have also raised the possibility that a f0+f2=2f1 resonance may act in triple mode pulsators.2006A&A...445..617Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/445/617CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/430/1049 : R Gem BV(RI)c differential photometry (Jurcsik+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/445/617https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/445/617http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/445/617https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/445/617https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/445/617http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/445/617GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/445/617/table1 (BVRI magnitudes of calibrating stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/445/617/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/445/617/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/445/617/table1?GETtext/xml+votable180.050000true1.2476419463.384118060.0055555555555555566/3066https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/445/617?format=asciiOpticalInfrareddefaultJ/A+A/445/617/table5Relative Ic magnitude of V823 Cas respect to GSC 04018-01777recnoRecord number assigned by the VizieR team.
