IR dust bubbles. II. Probing the detailed structure and young massive stellar populations of galactic H II regions. (2009)

Keywords : H II regions - infrared stars - stars: formation

Abstract: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 (2007, Cat. J/ApJ/670/428). We confirm that the structure identified in Watson et al. (2008ApJ...681.1341W) holds in less energetic bubbles, i.e., a photodissociated region, identified by 8um emission due to polycyclic aromatic hydrocarbons surrounding hot dust, identified by 24um emission and ionized gas, and identified by 20cm 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 ...(more)

GLIMPSE Point-Source Catalog (GPSC) is a 99.5% reliable catalog of point sources observed in the Spitzer-IRAC bands (3.6, 4.5, 5.8, and 8.0um). IRAC has a resolution of 1.5-1.9". MIPSGAL is a survey of the same region as GLIMPSE, using the MIPS instrument (24um and 70um) on Spitzer. MIPSGAL has a resolution of 6" at 24um and 18" at 70um. MAGPIS (Multi-Array Galactic Plane Imaging Survey) is a survey of the Galactic plane at 20cm and 6cm using the VLA in configurations B, C, and D combined with the Effelsburg 100m single-dish telescope. MAGPIS has a resolution of 6" at both wavelengths.
