Mixing in star-forming clouds explains why sibling stars look alike（图）
sibling star-forming clouds
2014/9/12
The chemical uniformity of stars in the same cluster is the result of turbulent mixing in the clouds of gas where star formation occurs, according to a study by astrophysicists at the University of Ca...
Observations and Analysis of High-Resolution Magnetic Field Structures in Molecular Clouds
Observations Analysis High-Resolution Magnetic Field Structures Molecular Clouds
2012/2/23
Recent high-angular-resolution (up to 0.7") dust polarization observations toward star forming regions are summarized. With the Sub-Millimeter Array, the emission from the dense structures is traced a...
Identification of Ambient Molecular Clouds Associated with Galactic Supernova Remnant IC443
Ambient Molecular Clouds Associated Galactic Supernova Remnant IC443
2012/2/23
The Galactic supernova remnant (SNR) IC443 is one of the most studied core-collapse SNRs for its interaction with molecular clouds. However, the ambient molecular clouds with which IC443 is interactin...
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 ...
