cds-question@unistra.frpolarimetryeclipsing-binary-starsWe present results from six years of recalibrated and new spectropolarimetric data taken with the University of Wisconsin's Half-Wave Spectropolarimeter and six years of new data taken with the photoelastic modulating polarimeter at the Flower and Cook Observatory of beta Lyrae. Combining these data with polarimetric data from the literature allows us to characterize the intrinsic BVRI polarized light curves. A repeatable discrepancy of 0.245 days (approximately 6hr) between the secondary minima in the total light curve and the polarization curve in the V band, with similar behavior in the other bands, may represent the first direct evidence for an accretion hot spot on the disk edge.2012ApJ...750...59Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/750/59CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/463/233 : UBV and radial velocity light curves of beta Lyr (Ak+, 2007)J/A+A/368/912 : Polarization & rotational velocities of Be stars (Yudin, 2001)J/A+A/312/879 : Beta Lyr radial velocities and UBV data (Harmanec+, 1996)J/AJ/110/1350 : Beta Lyrae light curve changes (Van Hamme+ 1995)J/A+AS/101/551 : Optical polarization of 1000 stars (Leroy 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/750/59https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/750/59http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/750/59https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/750/59https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/750/59http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/750/59GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/750/59/table3Flower and Cook Observatory (FCO) polarimetryrecnoRecord number assigned by the VizieR team.
