V light curve of AzV 73

DOI

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) and spectrographic data from Niemela & Bassino (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{deg} and a separation of 42R_{sun}. The sizes and masses are R_1=11.53 +/-0.5R_{sun}, M_1=25.26+/-0.7M_{sun}, and R_2=15.46+/-0.4R_{sun}, M_2=21.96+/-0.8M_{sun}_ for the primary and secondary components, respectively.
