cds-question@unistra.freclipsing-binary-starscataclysmic-variable-starsphotometryWe present new time-resolved photometry of 74 cataclysmic variables (CVs), 47 of which are eclipsing. Thirteen of these eclipsing systems are newly discovered. For all 47 eclipsing systems, we show high cadence (1-20s) light curves obtained with the high-speed cameras ULTRACAM and ULTRASPEC. We provide new or refined ephemerides, and supply mid-eclipse times for all observed eclipses. We assess the potential for light-curve modelling of all 47 eclipsing systems to determine their system parameters, finding 20 systems that appear to be suitable for future study. Systems of particular interest include V713 Cep, in which we observed a temporary switching-off of accretion; and ASASSN-14mv and CSS111019:233313-155744, which both have orbital periods well below the CV period minimum. The short orbital periods and light-curve shapes suggest that they may be double degenerate (AM CVn) systems or CVs with evolved donor stars.2017MNRAS.465.4968Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/465/4968CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/465/4968https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/465/4968http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/465/4968https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/465/4968https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/465/4968http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/465/4968GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/465/4968/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/465/4968/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/465/4968/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/465/4968/stars?GETtext/xml+votable180.050000true272.149208310.17497220.0055555555555555566/779 799 1761 2265 2507 2731 2765 3029 3476 4120 4173 4399 4479 4515 5064 5457 6076 6672 7040 7194 8575 8630 9747 10098 10242 11600 11931 12473 12646 12748 12767 12996 13249 13806 14781 15535 15590 15918 16253 17022 17685 18329 18381 18784 20313 20391 21862 22485 22493 22716 22771 22892 22901 22958 23301 23888 23924 25507 25683 27314 28370 29217 30770 31331 31361 31852 31863 32203 40255 40925 43804 47964 49029 49118https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/465/4968?format=asciidefaultJ/MNRAS/465/4968/starsList of studied starsNameObject namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
