Clustered Star Formation in Magnetic Clouds: Properties of Dense Cores Formed in Outflow-Driven Turbulence
Magnetic Clouds: Properties Dense Cores Formed Outflow-Driven Turbulence
2011/10/11
We investigate the physical properties of dense cores formed in turbulent, magnetized, parsec-scale clumps of molecular clouds, using three-dimensional numerical simulations that include protostellar ...
Stars at the Tip of Peculiar Elephant Trunk-Like Clouds in IC 1848E: A Possible Third Mechanism of Triggered Star Formation
ISM: HII regions — ISM: individual (IC 1848E) — ISM: kinematics and dynamics — stars: formation — stars: pre-main-sequence
2011/10/10
The HII region IC 1848 harbors a lot of intricate elephant trunk-like structures that look morphologically different from usual bright-rimmed clouds (BRCs). Of particular interest is a concentration o...
A Correlation Between Surface Densities of Young Stellar Objects and Gas in Eight Nearby Molecular Clouds
Stellar Objects Gas Nearby Molecular Clouds
2011/9/28
We report the discovery and characterization of a power law correlation between the local surface densities of Spitzer-identified, dusty young stellar objects and the column density of gas (as traced ...
