LS Pegasi: a low-inclination SW Sextantis-type cataclysmic binary with high-velocity Balmer emission-line wings.
TAYLOR C.J., THORSTENSEN J.R. and PATTERSON J.
Abstract (from CDS):
The high-velocity Balmer wings most probably arise from a stream reimpact point close to the white dwarf. We present simulated spectra based on a kinematic model similar to the modified disk-overflow scenario of Hellier & Robinson. The models reproduce the broad line wings, though some other details are unexplained.
Using an estimate of dynamical phase based on the model, we show that the phasing of the emission- and absorption-line variations is consistent with that in (eclipsing) SW Sex stars. We therefore identify LS Peg as a low-inclination SW Sex star.
Our model suggests i=30°, and the observed absence of any photometric signal at the orbital frequency establishes i<60°. This constraint puts a severe strain on interpretations of the SW Sex phenomenon which rely on disk structures lying slightly out of the orbital plane.
