Tc. Hillwig et al., SPECTROSCOPIC AND PHOTOMETRIC ANALYSIS OF THE NOVA-LIKE CATACLYSMIC VARIABLE PG 1000- A NEW VY SCULPTORIS STAR(667 ), The Astronomical journal, 115(5), 1998, pp. 2044-2046
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 ob
servations over a 35 month interval from Indiana University's robotic
telescope Robo-Scope show two drops of 3 mag to a low state. Spectrosc
opy shows a periodic velocity variation in the HE emission line with P
= 3.47 hr. This places the star just above the 2-3 hour period gap, w
hich supports the VY Sculptoris classification.
