Jv. Clausen et al., 4-COLOR PHOTOMETRY OF ECLIPSING BINARIES .37. LIGHT CURVES OF THE B-TYPE SYSTEM V539-ARAE, Astronomy & Astrophysics. Supplement series, 115(2), 1996, pp. 315-317
Accurate uvby light curves of the southern, detached, double-lined ecl
ipsing binary V539 Ara (HR 6622A, HD 161783, V = 5.(m)71, B3V + B4V, P
= 3.(d)17) are presented. They contain 1409 observations in each colo
ur, collected 1982-1984. Typical mean errors are 0.003-0.004 mag. Obse
rvations for 8 additional times of minima from 1985-1994 are included.
The secondary component belongs to the group of slowly pulsating B (o
r SPB) stars. An analysis of V539 Ara based on the new photometry and
the spectroscopic orbit by Andersen (1983) is published separately (Cl
ausen 1995).
