cds-question@unistra.frcataclysmic-variable-starsx-ray-binary-starsradial-velocityFrom a set of 13 cataclysmic binaries that were discovered in the Swift Burst Alert Telescope (BAT) survey, we conducted time-resolved optical spectroscopy and/or time-series photometry of 11, with the goal of measuring their orbital periods and searching for spin periods. Seven of the objects in this study are new optical identifications. Orbital periods are found for seven targets, ranging from 81 minutes to 20.4hr. PBC J0706.7+0327 is an AM Herculis star (polar) based on its emission-line variations and large amplitude photometric modulation on the same period. Swift J2341.0+7645 may be a polar, although the evidence here is less secure. Coherent pulsations are detected from two objects, Swift J0503.7-2819 (975s) and Swift J0614.0+1709 (1412s and 1530s, spin and beat periods, respectively), indicating that they are probable intermediate polars (DQ Herculis stars). For two other stars, longer spin periods are tentatively suggested. We also present the discovery of a 2.00hr X-ray modulation from RX J2015.6+3711, possibly a contributor to Swift J2015.9+3715, and likely a polar.2015AJ....150..170Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/170CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cb : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2014)II/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016)V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)I/322 : UCAC4 Catalogue (Zacharias+, 2012)I/317 : The PPMXL Catalog (Roeser+ 2010)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/AJ/149/128 : Radial velocities of 29 CVs (Thorstensen+, 2015)J/AJ/146/107 : Velocity curves of 10 cataclysmic binaries (Thorstensen+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/170https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/170http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/170https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/170https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/170http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/170GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/150/170/table1 (Stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/170/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/170/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/170/table1?GETtext/xml+votable180.050000true51.4142917-8.24522220.0055555555555555566/14641 15869 19178 20805 21338 22140 23946 24275 31873 34655 36721 38651 39753 40452https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/150/170?format=asciiOpticaldefaultJ/AJ/150/170/table1Stars observedSimbadNameSimbad column added by the CDSmeta.idcharClassClassification of star (4)meta.code;src.varcharNameStellar identifiermeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
