Abstract: | New spectrophotometric observations of the Wolf-Rayet system HD 50896 are presented and interpreted in terms of its binary
nature. The lines of N V, N IV and C IV show moderate variations, which can be explained using a binary model with a compact
companion. He n λ4686 appears to arise from a larger region compared to other lines. The distortion caused by the wind can
partly explain its flux variations. The emission fluxes of He I lines are generally constant indicating their non-participation
in the orbit. The results are compared with other Wolf-Rayet binaries (V444 Cyg and CQ Cep) and the evolutionary status is
discussed. |
