“Mapping the Environments of Massive Stars: A chapter in the story of the interrelated cosmos"

Presentation Abstract:

Scientists are curious people.  One of the things that most fascinates me is how we know the things that we claim to know.  Astronomical study is an excellent subject in which to explore this fascination, since in the effort to understand the history of the universe and its future trajectory, humans are limited to surveying the heavens from only the Earth.  Consequently, astronomers employ methods that involve multi-wavelength and temporal approaches for piecing together the story of the cosmos.  One aspect of this is the disproportionate impact that massive stars have for cosmic evolution.  In particular, many outstanding questions regarding the impacts of mass-loss for this chapter of cosmic history remain.  I discuss recent efforts at discerning the environments of mass stars - winds, shells, clumps, disks, and other structures - for resolving these outstanding issues.
