Description:
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 (1983A&A...118..255A 1983A&A...118..255A)
is published separately (Clausen 1995).
