We report the discovery of six infrared stellar wind bow shocks in the Galactic massive star formation regions M17 and RCW 49 from Spitzer GLIMPSE (Galactic Legacy Infrared Mid-Plane Survey Extraordinaire) images. The Infrared Array Camera (IRAC) on the Spitzer Space Telescope clearly resolves the arc-shaped emission produced by the bow shocks. We combine Two Micron All-Sky Survey (2MASS), Spitzer, MSX, and IRAS observations to obtain the spectral energy distributions (SEDs) of the bow shocks… Expand
