cds-question@unistra.frvariable-starscataclysmic-variable-starsnovaeradial-velocityWe report follow-up studies of 35 recently discovered cataclysmic variables (CVs), 32 of which were found in large, automated synoptic sky surveys. The objects were selected for observational tractability. For 34 of the objects, we present mean spectra and spectroscopic orbital periods, and for one more we give an eclipse-based period. Thirty-two of the period determinations are new, and three of these refine published estimates based on superhump periods. The remaining three of our determinations confirm previously published periods. Twenty of the stars are confirmed or suspected dwarf novae with periods shorter than 3 hr, but we also find three apparent polars (AM Her stars) and six systems with P>5hr. Five of these systems have secondary stars visible in their spectra, from which we estimate distances when possible. The orbital period distribution of this sample is very similar to that of previously discovered CVs.2016AJ....152..226Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/226CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cb : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2014)I/329 : URAT1 Catalog (Zacharias+ 2015)I/317 : The PPMXL Catalog (Roeser+ 2010)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/AJ/150/170 : Radial velocities of 7 cataclysmic binaries (Halpern+, 2015)J/MNRAS/443/3174 : 72 faint CV candidates in CRTS (Breedt+, 2014)J/MNRAS/441/1186 : Cataclysmic variables from CRTS (Drake+, 2014)J/ApJS/213/9 : Catalina Surveys periodic variable stars (Drake+, 2014)J/AJ/146/107 : Velocities of 10 cataclysmic binaries (Thorstensen+, 2013)J/AJ/144/81 : Spectroscopy and photometry of CV cand.
