Title: The Structure of Mass Loss from Massive Stars
Abstract: We propose to complete a survey of the mass outflows of luminous and massive stars, including interacting binary systems, luminous blue variables, OB supergiants, and Wolf-Rayet stars. The properties of the outflows in these systems will be measured using integral field spectroscopy of the He I (lambda) 10830 emission line. These Gemini North / NIFS observations will document the incidence of emission among a diverse group of stars, the origin of the emission in disks, winds, or nebular surroundings, and determine candidate systems for follow-up high angular resolution, adaptive optics observations. The work will show how the interstellar medium is enriched by mass loss processes associated with a number of key stages in the lives of massive stars.
