Scientific paper

We propose to obtain partial spectral line images, using Spitzer/IRS, of four carefully selected Galactic infrared bubbles (detected in the GLIMPSE survey) that have different morphologies and are believed to represent different stages of evolution. The main goals of this program are to: test and constrain dynamical evolution models of bubbles produced by young O-stars. Temperature, density, and velocity structure are predicted to change by orders of magnitude with age and with radius from the central star(s). Confirmation of these predictions has had limited success because of limitations imposed by extinction, sensitivity, spatial resolution, and access to probes that sample a wide range of ionization. IRS is ideally suited to detect and measure the radii of the various ionization zones and transition regions within stellar wind-blown bubbles. We propose to do this by obtaining spectral line images of a strip across the diameter of the four selected bubbles.
