Scientific paper

We have obtained photometric and spectroscopic observations of the suspected cataclysmic variable stars VW Tucanae, Phe 1, and Scl 2. VW Tuc and Phe 1 are confirmed as cataclysmic variables (CVs). VW Tuc has the spectrum of a ``normal,'' disk-accreting CV. Phe 1 is a double-lined spectroscopic binary that may have a short orbital period-a time-resolved spectroscopic study of the kinematics in this system could have important implications to the understanding of CV structure and evolution. Scl 2 appears to be a non-CV composed of a late-type dwarf emission (dMe) star with a (noninteracting) white dwarf or hot subdwarf companion.
