Context. Density and velocity fluctuations on virtually all scales observed with modern telescopes show that molecular clouds (MCs) are turbulent. The forcing and structural …

We present results of large-scale three-dimensional simulations of supersonic Euler turbulence with the piecewise parabolic method and multiple grid resolutions up to 2048 3 …
We live in an age in which high-performance computing is transforming the way we do science. Previously intractable problems are now becoming accessible by means of …
C Federrath, RS Klessen, W Schmidt - The Astrophysical Journal, 2009 - iopscience.iop.org
In a systematic study, we compare the density statistics in high-resolution numerical experiments of supersonic isothermal turbulence, driven by the usually adopted solenoidal …

This study presents an alternative way to perform large eddy simulation based on a targeted numerical dissipation introduced by the discretization of the viscous term. It is shown that this …
It is shown that the use of a high power α of the Laplacian in the dissipative term of hydrodynamical equations leads asymptotically to truncated inviscid conservative dynamics …
A study is made about the energy spectrum E (k) of turbulence on the basis of high- resolution direct numerical simulations (DNSs) of forced incompressible turbulence in a …

Abstract The Padoan and Nordlund model of the stellar initial mass function (IMF) is derived from low-order statistics of supersonic turbulence, neglecting gravity (eg, gravitational …

We measure the turbulent diffusion coefficient of dust grains embedded in magnetorotational turbulence in a protoplanetary disk directly from numerical simulations and compare it to the …
