Observations of rapid blue variables - XVI. VZ Sculptoris.
Abstract
High speed photometry of the fifteenth magnitude nova-like variable VZ Scl is reported. The light curve resembles that of DQ Her and U Gem. An improved period of od.i446222o is derived. Measurements of oo-in. spectra provide a radial velocity curve. Apparent maximum velocity occurs near mid-eclipse, and the velocity curve is markedly non-sinusoidal. These features are interpreted as effects of a hot spot in the system.
