Investigating the Sloan Digital Sky Survey Cataclysmic Variable SDSS J132723.39+652854.2*

Photometric and spectroscopic observations reveal the Sloan Digital Sky Survey cataclysmic variable SDSS J132723.39+652854.2 to be a likely SW Sex star with an orbital period of P = 3.28 hr. The Sloan Digital Sky Survey spectrum shows strong He i, He ii, and Balmer emission lines. Time-resolved spectra acquired at Apache Point Observatory reveal absorption-line structure within the emission lines near phase 0.5. Photometric data obtained at Manastash Ridge Observatory using Harris V and B filters reveal a high-inclination system (i = 80°) with deep (~2 mag) eclipses. The orbital period and the spectral variations favor an SW Sex interpretation.
