Accepted: 5 October 2001
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. ([CITE]) and spectrographic data from Niemela & Bassino ([CITE]), by means of the Wilson-Devinney code. It is found that this system is semi-detached, with an orbital inclination of roughly and a separation of . The sizes and masses are , , and , for the primary and secondary components, respectively.
Key words: binaries: eclipsing / stars: early-type / stars: fundamental parameters / stars: individual: AzV 73
