The radial velocities and the photometric data obtained by $Hipparcos$ were analysed for deriving the astrophysical parameters of the components. Masses and radii were determined as M$_p$=17.94$\\pm$1.16 M$_{\\odot}$ and R$_p$=8.33$\\pm$0.29 R$_{\\odot}$, M$_s$=2.64$\\pm$0.30 M$_{\\odot}$ and R$_s$=2.13$\\pm$0.10 R$_{\\odot}$ for the components of V446\\,Cep. Our analyses show that V446\\,Cep is a detached Algol-type system. Based on the position of the components plotted on the theoretical Hertzsprung-Russell diagram, we estimate that the age of V446\\,Cep is about 10 Myr, neglecting the effects of mass-loss and mass exchange between the components. Using the UBVJHK magnitudes and interstellar absorption we estimated the mean distance to the system V446\\,Cep as 1100$\\pm$62\\,pc.", "revisions": [ { "version": "v1", "updated": "2014-06-02T11:37:29.000Z" } ], "analyses": { "keywords": [ "massive eclipsing binary", "complex analysis", "stellar binary", "association", "components" ], "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1406.0499C" } } }
