Spectroscopic and Photometric Analysis of the Nova-like Cataclysmic Variable PG 1000+667: A New VY Sculptoris Star

Multiyear photometry and orbit-resolved spectroscopy of the nova-like cataclysmic variable PG 1000+667 show behavior associated with the VY Sculptoris subclass of nova-like cataclysmic variables. Photometric observations over a 35 month interval from Indiana University's robotic telescope RoboScope show two drops of 3 mag to a low state. Spectroscopy shows a periodic velocity variation in the Hβ emission line with P = 3.47 hr. This places the star just above the 2–3 hour period gap, which supports the VY Sculptoris classification.
