optically thick wind
  باد ِ نورانه ستبر  
bâd-e nurâné setabr
Fr.: vent optiquement épais  

A wind with the → sonic point located at large optical depth for continuum. In particular, → Wolf-Rayet star winds are → optically thick. However, the outer parts of W-R winds are → optically thin for continuum, and in those regions the matter flow is driven by the same mechanism as in the winds of OB stars.

See also: → optically; → thick; → wind.
