Influence of Cooling-Induced Compressibility on the Structure of Turbulent Flows and Gravitational Collapse
E. Vazquez-Semadeni, T. Passot, A. Pouquet
We investigate the properties of highly compressible turbulence, the compressibility arising from a small effective polytropic exponent due to cooling. In the limit of small…
MHD Turbulence, Cloud Formation and Star Formation in the ISM
E. Vazquez-Semadeni, T. Passot, A. Pouquet
We discuss the role of turbulence in cloud and star formation, as observed in numerical simulations of the interstellar medium. Turbulent compression at the interfaces of colliding…
A Turbulent Model for the Interstellar Medium. II. Magnetic Fields and Rotation
T. Passot, E. Vazquez-Semadeni, A. Pouquet
We present results from two-dimensional numerical simulations of a supersonic turbulent flow in the plane of the galactic disk, incorporating shear, thresholded and discrete star f…
