Abstract (from CDS):

We present an analysis of late-O/early-B-powered, parsec-sized bubbles and associated star formation using Two Micron All Sky Survey, GLIMPSE, MIPSGAL, and MAGPIS surveys. Three bubbles were selected from the Churchwell et al. catalog. We confirm that the structure identified in Watson et al. holds in less energetic bubbles, i.e., a photodissociated region, identified by 8 µm emission due to polycyclic aromatic hydrocarbons surrounding hot dust, identified by 24 µm emission and ionized gas, and identified by 20 cm continuum. We estimate the dynamical age of two bubbles by comparing bubble sizes to numerical models of Hosokawa and Inutsuka. We also identify and analyze candidate young stellar objects using spectral energy distribution (SED) fitting and identify sites of possible triggered star formation. Lastly, we identify likely ionizing sources for two sources based on SED fitting.
