- W2169310659 abstract "A spectroscopic study of the binary Wolf–Rayet (WR)+O system WR 145 is performed, in order to determine the radial velocity orbits of the individual stars, the angle of orbital inclination and the stellar masses. The emission and absorption components are separated from the original spectra, allowing us to confirm the spectral classification WN 7o/CE of the hybrid WR component and to derive a spectral classification O7V((f)) for the O star. A study of the wind-collision properties is performed. Fitting the radial velocity and full width at half-maximum of the excess emission with Lührs’ model results in an inclination angle of i= 63°, leading to estimates of the stellar masses: MWR= 18 M⊙ and MO= 31 M⊙. Both of these masses are compatible with those of other stars of similar types." @default.
