Investigation of the Magellanic eclipsing binary HV 2241.
OSTROV P.G., MORRELL N.I. and LAPASSET E.
Abstract (from CDS):
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±0.7M☉, R1=14.9±0.4R☉, M2=18.4 ±0.7M☉ and R2=13.7±0.4R☉. We review the spectral classification analysing HST and IUE data and discuss the temperature and the reddening for this star.
