Mass loss effects in the spectrum of the O 6.5f binary HD 153919
Description
Apart from the known P-Cygni profiles of Hβ, HeI 5876, 4471 in the spectrum of HD 153919, also HeII 3923 and a line at 3759 A which is tentatively identified as OIII show an emission component. These lines indicate that the Of star is losing mass at a high rate. A detailed analysis of the radial velocities obtained from 76 spectrograms indicates that the outflow of the wind is not spherically symmetric: at the side where the Of star faces its companion the velocity of the wind has increased.
