cds-question@unistra.frvariable-starsphotometryeclipsing-binary-starsWe analyze eight years (1999-2007) of automated photometric observations of the active Algol binary UX Monocerotis (HD 65607; P=5.90day; A5III-IVe+G2III) to search for mass transfer bursts similar to those seen in U Cephei. The largest photometric anomaly is the mean gainer luminosity difference between the stream-impact hemisphere and the opposite hemisphere. We find an updated Wilson-Devinney solution for earlier six-color observations. The UX Mon donor star fills its Roche lobe and the gainer nearly fills its rotational lobe. Instead of isolated bursts of the U Cep type, we found nearly continuous brightness fluctuations likely produced by variable mass transfer.2009AJ....138.1435Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/138/1435CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2012)III/231 : The Tycho-2 Spectral Type Catalog (Wright+, 2003)II/168 : Homogeneous Means in the UBV System (Mermilliod 1991)J/A+A/446/785 : Catalogue of eclipsing variables (Malkov+, 2006)J/AJ/106/2096 : Limb-darkening coefficients in binaries (Van Hamme 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/138/1435https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/138/1435http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/138/1435https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/138/1435https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/138/1435http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/138/1435GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/138/1435/table1Iybvuri observations of UX MonocerotisrecnoRecord number assigned by the VizieR team.
