cds-question@unistra.frvariable-starsgiant-starss-starsinfrared-photometryvisible-astronomybroad-band-photometryWe present FCAPT differential Johnson BV and Cousins RI photometry and radial velocities of the S-type AGB stars RS Cnc, ST Her, OP Her and HR Peg. We performed multiperiodic analyses of this photometry to learn about the frequencies of variability. The B, V, R, and I light curves are generally in phase. RS Cnc has periods of order 122 and 248 days. Repeating the analyses using our data with the extensive V and R photometry of Percy et al. (2001PASP..113..983P) shows several periods near 248 days and a period near 135 days. The primary period of ST Her appears to be about 144 days although it is manifested most readily by its 103 day alias. OP Her and HR Peg exhibit periods, respectively, of about 416 and 116 days and of 54 and 74 days. The differences between our data set and the larger one of Percy et al. (2001PASP..113..983P) for RS Cnc raises important questions about multiperiodic analyses for AGB stars.2005BaltA..14...41Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/BaltA/14/41CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/BaltA/14/41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/BaltA/14/41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/BaltA/14/41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/BaltA/14/41https://vizier.iucaa.in/viz-bin/votable?-source=J/BaltA/14/41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/BaltA/14/41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/BaltA/14/41/table2Photometry of RS CncrecnoRecord number assigned by the VizieR team.
