Instability and Variability of Hot-Star Winds [E-Book] : Proceedings of an International Workshop Held at Isle-aux-Coudres, Quebec Province, Canada 23–27 August, 1993 / edited by Anthony F. J. Moffat, Stanley P. Owocki, Alex W. Fullerton, Nicole St-Louis.
This specialized workshop was conceived during the workshop on "Non isotropic and Variable Outflows from Stars", which was held at the Space Telescope Science Institute in October, 1991. At that meeting, the four of us collectively decided that the time was ripe for an even more focussed...
