Session 19 - Hot Stars.
Display session, Monday, January 15
North Banquet Hall, Convention Center
We discuss why B supergiant winds are particularly well suited for wind variability studies, and then present a gallery of dynamic spectra which demonstrate the range of wind variability observed in B supergiants. The examples suggest the presence wind compressed disks, bifurcated winds, shock formation, rotationally modulated winds and the spontaneous generation of wind enhancements. They underscore the strength and richness of wind variability in B supergiants and the challenges these phenomena present to theoretical studies of stellar winds.
