- Abstract
The Bulge Asymmetries and Dynamic Evolution (BAaDE) project attempts to improve our knowledge about the structure and dynamics of the inner Milky Way galaxy by sampling tens of thousands of infrared color-selected evolved stars with circumstellar envelopes (CSEs). The SiO masers in these CSEs yield the object's line-of-sight velocity instantly and accurately, and together provide a sample of point-mass particles that are complementary to high-mass star formation masers typically found in the Galactic Disk as well as to optical samples that cannot reach into the Galactic Plane and Bulge due to extremely high visual extinction. This presentation introduces the BAaDE survey and highlights current results.
