Abstract:
A CCD V light curve for the eclipsing binary star AzV 73 is presented.
This new photometric observations are analysed together with
previously published CCD I photometry from Udalski et al.
(1998AcA....48..563U 1998AcA....48..563U) and spectrographic data from Niemela & Bassino
(1994ApJ...437..332N 1994ApJ...437..332N), by means of the Wilson-Devinney code. It is
found that this system is semi-detached, with an orbital inclination
of roughly 86° and a separation of 42R☉. The sizes and
masses are R1=11.53 ±0.5R☉, M1=25.26±0.7M☉, and
R2=15.46±0.4R☉, M2=21.96±0.8M☉ for the primary and
secondary components, respectively.
