Chemical Variation in Molecular Cloud Cores in the Orion A Cloud
Chemical Variation Molecular Cloud Cores the Orion A Cloud
2011/1/10
We have observed molecular cloud cores in the Orion A giant molecular cloud (GMC) in CCS, HC3N, DNC, and HN13C to study their chemical characteristics. We have detected CCS in the Orion A GMC for the ...
On the interaction of a thin, supersonic shell with a molecular cloud
supersonic shell with molecular cloud
2011/1/10
Molecular clouds (MCs) are stellar nurseries, however, formation of stars within MCs depends on the ambient physical conditions. MCs, over a free-fall time are exposed to numerous dynamical phenomena,...
We study the mass-density relationship n m^x in molecular cloud clumps, considering various relations between the gravitational, kinetic, internal and magnetic energy. Clumps are described statistical...
Theory of Feedback in Clusters and Molecular Cloud Turbulence
Feedback in Clusters Molecular Cloud Turbulence
2011/1/11
I review recent numerical and analytical work on the feedback from both low- and high-mass cluster stars into their gasoeus environment. The main conclusions are that i) outflow driving appears capabl...
New Panoramic View of $^{12}$CO and 1.1 mm Continuum Emission in the Orion A Molecular Cloud. I. Survey Overview and Possible External Triggers of Star Formation
Galaxy Astrophysics (astro-ph.GA)
2011/1/6
We present new, wide and deep images in the 1.1 mm continuum and the $^{12}$CO ($J$=1-0) emission toward the northern part of the Orion A Giant Molecular Cloud (Orion-A GMC). The 1.1 mm data were take...
EVOLUTION OF DENSITY PERTURBATIONS IN A CYLINDRICAL MOLECULAR CLOUD USING SMOOTHED PARTICLE HYDRODYNAMICS
ISM: clouds evolution ISM: magnetic fields Stars: formation Methods: numerical
2010/10/29
Molecular clouds have a hierarchical structure from few tens of
parsecs for giants to few tenth of a parsec for proto-stellar cores. Nowadays, our
observational techniques are so advanced that it ha...
