dc.description.abstract | We present a CCD V light curve of HV 2241, together with some observations in the B band. We analysed our photometric data jointly with previously published radial velocities by means of the Wilson-Devinney code, and derived new values for the physical parameters of this massive eclipsing binary system. We confirm that this system is semi-detached, with the secondary (less massive and less luminous component) filling its Roche-lobe. From our analysis, we estimate the following masses and radii for the components of HV 2241: M1 = 36.2 ± 0.7 M⊙, R1 = 14.9 ± 0.4 R⊙, M2 = 18.4 ± 0.7 M⊙ and R2 = 13.7 ± 0.4 R⊙. We review the spectral classification analysing HST and IUE data and discuss the temperature and the reddening for this star. | en |
