Abstract (from CDS):

Accurate uvby light curves of the southern, detached, double-lined eclipsing binary V539 Ara (HR 6622A, HD 161783, V=5.71mag , B3V+B4V, P=3.17d) are presented. They contain 1409 observations in each colour, collected 1982-1984. Typical mean errors are 0.003-0.004mag. Observations for 8 additional times of minima from 1985-1994 are included. The secondary component belongs to the group of slowly pulsating B (or SPB) stars. An analysis of V539 Ara based on the new photometry and the spectroscopic orbit by Andersen (1983) is published separately (Clausen 1995).
