Massive Star Formation via the Collapse of Subvirial and Virialized Turbulent Massive Cores
Anna L. Rosen, Pak Shing Li, Qizhou Zhang +1
Similar to their low-mass counterparts, massive stars likely form via the collapse of pre-stellar molecular cores. Recent observations suggest that most massive cores are subvirial…
Compressed magnetic field in the magnetically-regulated global collapsing clump of G9.62+0.19
Tie Liu, Kee-Tae Kim, Sheng-Yuan Liu +22
How stellar feedback from high-mass stars (e.g., H{\sc ii} regions) influences the surrounding interstellar medium and regulates new star formation is still unclear. To address thi…
Ambipolar Diffusion Heating in Turbulent Systems
Pak Shing Li, Andrew Myers, Christopher F. McKee
The temperature of the gas in molecular clouds is a key determinant of the characteristic mass of star formation. Ambipolar diffusion (AD) is considered one of the most important h…
Sub-Alfvenic Non-Ideal MHD Turbulence Simulations with Ambipolar Diffusion: III. Implications for Observations and Turbulent Enhancement
Pak Shing Li, Christopher F. McKee, Richard I. Klein
Ambipolar diffusion (AD) is believed to be a crucial process for redistributing magnetic flux in the dense molecular gas that occurs in regions of star formation. We carry out nume…
Comparing Numerical Methods for Isothermal Magnetized Supersonic Turbulence
Alexei G. Kritsuk, Aake Nordlund, David Collins +13
We employ simulations of supersonic super-Alfvenic turbulence decay as a benchmark test problem to assess and compare the performance of nine astrophysical MHD methods actively use…
Sub-Alfvenic Non-Ideal MHD Turbulence Simulations with Ambipolar Diffusion: II. Comparison with Observation, Clump Properties, and Scaling to Physical Units
Christopher F. McKee, Pak Shing Li, Richard I. Klein
Ambipolar diffusion is important in redistributing magnetic flux and in damping Alfven waves in molecular clouds. The importance of ambipolar diffusion on a length scale is…
