cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomyWide-band photometryearly-type-starsWe analyze photometric and spectroscopic data and study the orbital period of the early-type interacting binary system V382 Cyg by using all the available data. We obtain a simultaneous light and radial velocity curve solution. The derived physical parameters of the primary and secondary stellar components are M_1_=27.9(5)M_{sun}_, M_2_=20.8(4)M_{sun}_, R_1_=9.7(2)R_{sun}_, R_2_=8.5(2)R_{sun}_, log(L_1_/L_{sun}_)=5.152(20), and log(L_2_/L_{sun}_)=4.954(19) while the separation of the components is a=23.4R_{sun}_. Newly obtained parameters yield the distance of the system to be 1466(76)pc. Analyses of the mid-eclipse times indicate a period increase of dP/dt=4.2(1)x10^-7^days/yr that can be interpreted in terms of the high-mass transfer (dM/dt=6.1(5)x10^-6^M_{sun}_/yr) from the less massive component to the more massive component. Finally, we model the evolution of the components using non-conservative codes and discuss the results obtained. The age of the binary system is estimated to be 3.85Myr.2013AJ....145....9Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/9CatalogResearchIsServedByTAP VizieR generic servicerelated-toV/119 : Catalogue of field contact binary stars (Pribulla+, 2003)II/233 : Tycho variables stars (Piquard 2001)I/259 : The Tycho-2 Catalogue (Hog+ 2000)V/120 : Catalog of early-type contact binaries (Bondarenko+, 1996)J/AN/334/860 : Catalogue of eclipsing variables.
