cds-question@unistra.frvariable-starssupergiant-starsinfrared-photometryWe have analyzed our long-term (1995-2008) JHKLM photometry for three variable RV Tau supergiants. It follows from this analysis that: the amplitude of the JHK brightness variations is approximately the same, 0.9-1mag, for the three stars; a negative linear trend is noticeable in the variations of the mean J brightness for AC Her; and the mean J brightness of R Sct and V Vul remained constant. The observed J brightness fluctuations in the supergiants are shown to be consistent either only with the temperature pulsations (AC Her and V Vul) or with the temperature and radial pulsations (R Sct).2010PAZh...36..144Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/36/144CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/36/144https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/36/144http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/36/144https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/36/144https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/36/144http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/36/144GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/PAZh/36/144/table2Infrared photometry for the objects under studyrecnoRecord number assigned by the VizieR team.
