Abstract:
We obtained time-series radial-velocity spectroscopy of 20 cataclysmic
variable stars, with the aim of determining orbital periods Porb.
All of the stars reported here prove to have Porb>3.5h. For 16 of
the stars, these are the first available period determinations, and
for the remaining four (V709 Cas, AF Cam, V1062 Tau, and RX J2133+51),
we use new observations to improve the accuracy of previously
published periods. Most of the targets are dwarf novae, without
notable idiosyncrasies.
Description:
Our spectroscopic observations are from the 2.4m Hiltner or 1.3m
McGraw-Hill telescopes at MDM Observatory in Kitt Peak, Arizona.

Note (1): Positions should be accurate to ∼0.1".
Note (2): The three numbers given in the References column are, respectively,
the sources for the celestial position, the variability type, and the
magnitude range. Most of the positions are measured from direct CCD images
taken at MDM, with coordinate solutions derived from fits to the UCAC2
(Zacharias et al., 2004, Cat. I/289) or USNO-A2.0 (Monet et al. 1996,
Cat. I/252).
