cds-question@unistra.frvariable-starsvisible-astronomyspectroscopyradial-velocityWe report spectroscopic observations of seven bright southern cataclysmic variable stars, collected on a single two-week observing run using the 1.9m Radcliffe telescope at the South African Astronomical Observatory. We used a radial-velocity time series, in some cases in combination with other data, to determine or clarify orbital periods for five of them, namely ATOJ061.1478-31.0634, BMAM-V547, MGAB-V202, NSV4202, and V1147Cen. For BMAM-V547, we use data from the Transiting Exoplanet Survey Satellite (TESS) to corroborate and sharpen the orbital period; the TESS data also show a photometric period near 3.93days, likely indicating precession of the accretion disk. Also, we find a periodic modulation in the radial velocities of the SU UMa-type dwarf nova Var Ret2005, but are unable to specify a unique cycle count. Finally, we show a spectrum of ASASSN-VJ061528.41-412007.3 that appears typical of a luminous novalike variable.2023AJ....166..131Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/166/131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/other/IBVS/5863 : 79th Name-List of Variable Stars (Kazarovets+, 2008)J/ApJ/696/870 : Catalina Real-time Transient Survey (CRTS) (Drake+, 2009)J/ApJS/194/28 : The evolution of cataclysmic variables (Knigge+, 2011)J/MNRAS/435/707 : H{alpha} velocity curves of IM Eri (Armstrong+, 2013)J/ApJ/788/48 : X-ray through NIR photometry of NGC 2617 (Shappee+, 2014)J/AcA/65/313 : Thousand new dwarf novae from the OGLE Survey (Mroz+, 2015)J/AJ/160/151 : RVs 5 cataclysmic variable candidates (Thorstensen, 2020)J/AJ/160/6 : OSMOS &modspec RVs of 30 catac variable (Thorstensen, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/166/131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/166/131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/166/131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/166/131https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/166/131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/166/131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/166/131/table1 (List of objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/166/131/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/166/131/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/166/131/table1?GETtext/xml+votable180.050000true61.14784583-31.063438890.0055555555555555566/33265 34702 37101 39063 39272 39591 43235https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/166/131?format=asciiOpticaldefaultJ/AJ/166/131/table1List of objectsrecnoRecord number assigned by the VizieR team.
