cds-question@unistra.frmultiple-starsinfrared-photometryvisible-astronomybroad-band-photometrypolarimetryThe results of multi-year photometric and polarimetric observations of the young binary system DF Tau in UBVRI bands as well as bispectrum speckle interferometric observations in the H and K bands are presented. The photometric and polarimetric observations suggest the linear poarization variation has substantially a stochastic character.2006A&A...448.1075Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/448/1075CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/101/485 : Multisite UBVRI photometry in Tau-Aur cloud (Bouvier+ 1993)J/A+A/327/145 : Photopolarimetric activity of RR Tauri (Rostopchina+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/448/1075https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/448/1075http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/448/1075https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/448/1075https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/448/1075http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/448/1075GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/448/1075/table1DF Tau photometric and polarimetric UBVRI observations at CAOrecnoRecord number assigned by the VizieR team.
