摘要: The rate of mass loss in the from cold dense gas a wide Wolf-Rayet binary like WR 140 is estimated. At some distance binary, this can form dust shell and reradiate UV radiation IR region. In case which has high eccentricity observed outbursts may be caused by strong increase outflow at periastron
