Abstract:
First multicolour photoelectric light curves of the eclipsing binaries
AQ Tuc and AY Vel obtained in 1965 and 1969 at the Leiden Southern Station
using Walraven VBLU filters were analyzed by the Wilson-Devinney's code.
Our analysis confirmed the contact configuration for AQ Tuc and revealed
that AY Vel is an almost contact system with q approx. 3. The absolute radii
of the components of AQ Tuc derived from the combination of our photometric
and available spectroscopic elements are R_1 = 2.03 +/- 0.11 R_Sun and
R_2 = 1.30 +/- 0.07 R_Sun.
