Resumo

We studied the environment of the dust bubble N10 in molecular emission. Infrared bubbles, first detected by the GLIMPSE survey at 8.0 mu m, are ideal regions to investigate the effect of the expansion of the H II region on its surroundings and the. eventual triggering of. star formation at its borders. In this work, we present a multi-wavelength study of N10. This bubble is especially interesting because. infrared studies of the young stellar content suggest a scenario of ongoing star formation, possibly triggered. on the edge of the H II region. We carried out observations of (CO)-C-12(1-0) and (CO)-C-13(1-0) emission at PMO 13.7 m toward. N10. We also analyzed the IR and sub-millimeter emission on this region and compare those different tracers to obtain a detailed view of the interaction between the expanding H II region and the molecular gas. We also estimated the parameters of the denser cold dust condensation and the ionized gas inside the shell. Bright CO emission was detected and two molecular clumps were identified. from which we have derived physical parameters. We also estimate the parameters for the densest cold dust condensation and for the ionized gas inside the shell. The comparison between the dynamical age of this region and the fragmentation timescale favors the ``Radiation-Driven Implosion{''} mechanism of star formation. N10 is a case of particular interest with gas structures in a narrow frontier between the. H II region and surrounding molecular material, and with a range of ages of YSOs situated in the region, indicating triggered star formation. (AU)
