The B Supergiant Components of the Double‐lined Binary HD 1383
The B Supergiant Components of the Double‐lined Binary HD 1383
We present new results from a study of high quality, red spectra of the massive binary star system HD 1383 (B0.5 Ib + B0.5 Ib). We determined radial velocities and revised orbital elements (P = 20.28184 +/- 0.0002 d) and made Doppler tomographic reconstructions of the component spectra. A comparison …
