cds-question@unistra.frmultiple-starsinfrared-photometryvisible-astronomyWide-band photometryWe present UBVR photometric observations of the 96-day binary system UU Cancri (K4 III) obtained in 1972-1994. A relatively large scatter in the orbital light curves turned out to be intrinsic with a modulating cycle lasting at least 8000 days. Using all available archived photographic and visual observations covering nearly 100 years, we find the orbital period of the system to be constant. This fact, together with the pattern of the colour curves, makes the existence of a powerful accretion disk in the system improbable.2007JAD....13....2Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/JAD/13.2CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/JAD/13.2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/JAD/13.2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/JAD/13.2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/JAD/13.2https://vizier.iucaa.in/viz-bin/votable?-source=J/other/JAD/13.2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/JAD/13.2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/other/JAD/13.2/table5Differential magnitudes of UU CancrirecnoRecord number assigned by the VizieR team.
