Rapid Molecular Cloud and Star Formation: Mechanisms and Movies
Fabian Heitsch, Lee Hartmann
We demonstrate that the observationally inferred rapid onset of star formation after parental molecular clouds have assembled can be achieved by flow-driven cloud formation of atom…
Fragmentation of Shocked Flows: Gravity, Turbulence and Cooling
F. Heitsch, L. Hartmann, A. Burkert +1
The observed rapid onset of star formation in molecular clouds requires rapid formation of dense fragments which can collapse individually before being overtaken by global gravitat…
Fast dynamos in weakly ionized gases
Ellen G. Zweibel Fabian Heitsch
The turnover of interstellar gas on yr timescales argues for the continuous operation of a galactic dynamo. The conductivity of interstellar gas is so high that the dyna…
Evolution of Unmagnetized and Magnetized Shear Layers
M. L. Palotti, F. Heitsch, E. G. Zweibel +1
We present numerical simulations of the growth and saturation of the Kelvin-Helmholtz instability in a compressible fluid layer with and without a weak magnetic field. In the absen…
Advanced numerical methods in astrophysical fluid dynamics
A. Hujeirat, B. W. Keil, F. Heitsch
Computational gas dynamics has become a prominent research field both in astrophysics and cosmology. In the first part of this review we intend to briefly describe several of the n…
Cooling, Gravity and Geometry: Flow-driven Massive Core Formation
Fabian Heitsch, Lee Hartmann, Adrianne D. Slyz +2
We study numerically the formation of molecular clouds in large-scale colliding flows including self-gravity. The models emphasize the competition between the effects of gravity on…
