cds-question@unistra.freclipsing-binary-starsccd-photometryo-starsA 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.2001A&A...380..258Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/380/258CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/380/258https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/380/258http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/380/258https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/380/258https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/380/258http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/380/258GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap3.322582951404819e-19 3.852589004194616e-19defaultJ/A+A/380/258/tableCCD light curve of AzV 73recnoRecord number assigned by the VizieR team.
