cds-question@unistra.freclipsing-binary-starsvisible-astronomybroad-band-photometryThe near-contact system RU UMi with an F0 primary and a K5 secondary was observed in U, B and V wavelengths in May and July 1998, as well as in March, May and July 1999. Six new observed times of minima are given and a new ephemeris is proposed. The basic parameters of the system extracted by our observations were used for spot modelling of the light curves. A simple spot distribution was determined, based on a model with one relatively small cool spot on the surface of the secondary. Absolute elements were calculated and the evolutionary status was determined. Our data favor a semi-detached configuration, with the secondary filling its inner Roche lobe; the primary must also be near the limits of its lobe.2001A&A...369..960Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/369/960CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/369/960https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/369/960http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/369/960https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/369/960https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/369/960http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/369/960GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/369/960/table2Normal points from UBV light curvesrecnoRecord number assigned by the VizieR team.
