cds-question@unistra.frvariable-starsphotometryThe results of a study of the integrated brightness of the SU UMa eclipsing binary V1239 Her are presented. The system was monitored on nine nights in 2013-2014 when the binary was in quiescence. The orbital period is refined (P_orb_=0.100082222(2)d) and the system's light curves obtained. These curves provide evidence for active processes in the system between outbursts: the depths of both minima and the amplitude of the pre-eclipse hump vary, and one of the light curves exhibits no hump at all. The parameters of the accretion disk, hot spot, and gas stream in V1239 Her for several epochs are determined in a "combined" model taking into account the contributions to the total radiation flux from the opaque part of the gas stream and the hot spot on the lateral surface of the disk.2015AZh....92..323Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/92/323CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/92/323https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/92/323http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/92/323https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/92/323https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/92/323http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/92/323GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AZh/92/323/table3Mean light curves of V1239 Her obtained in 2013-2014Phase[0/1] Phasetime.phasefloatrecnoRecord number assigned by the VizieR team.
