cds-question@unistra.frcataclysmic-variable-starsx-ray-binary-starsspectroscopyWe report on ground-based optical observations of 10 cataclysmic binaries that were discovered through their X-ray emission. Time-resolved radial velocity spectroscopy yields unambiguous orbital periods for eight objects and ambiguous results for the remaining two. The orbital periods range from 87 minutes to 9.38 hr. We also obtained time-series optical photometry for six targets, four of which have coherent pulsations. These periods are 1218s for 1RXSJ045707.4+452751, 628s for AXJ1740.2-2903, 477s for AXJ1853.3-0128, and 935s for IGRJ19267+1325. A total of seven of the sources have coherent oscillations in X-rays or optical, indicating that they are intermediate polars (DQ Herculis stars). Time-resolved spectroscopy of one object, SwiftJ2218.4+1925, shows that it is an AM Herculis star, or polar, and IGRJ19552+0044 may also be in that class. For another object, SwiftJ0746.2-1611, we find an orbital period of 9.384 hr and detect the spectrum of the secondary star. The secondary's spectral contribution implies a distance of 900 (+190, -150)pc, where the error bars are estimated using a Monte Carlo technique to account for correlated uncertainties.2013AJ....146..107Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/146/107CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cb : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2014)I/322 : UCAC4 Catalogue (Zacharias+, 2012)I/317 : The PPMXL Catalog (Roeser+ 2010)V/123 : Catalog of Cataclysmic Variables (Downes+ 2001-2006)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/AJ/144/81 : Spectroscopy and photometry of CV candidates (Thorstensen+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/146/107https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/146/107http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/146/107https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/146/107https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/146/107http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/146/107GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/146/107/table1 (Stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/146/107/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/146/107/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/146/107/table1?GETtext/xml+votable180.050000true74.284666745.46388890.0055555555555555566/1465 12627 21553 28849 28884 29509 30129 30306 30670 40635https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/146/107?format=asciiOpticaldefaultJ/AJ/146/107/table1Stars observedrecnoRecord number assigned by the VizieR team.
