The density variance-Mach number relation in isothermal and non-isothermal adiabatic turbulence

Nolan, Chris; Federrath, Christoph; Sutherland, Ralph


The density variance-Mach number relation of the turbulent interstellar medium is relevant for theoretical models of the star formation rate, efficiency, and the initial mass function of stars. Here we use high-resolution hydrodynamical simulations with grid resolutions of up to 10243 cells to model compressible turbulence in a regime similar to the observed interstellar medium. We use FYRIS ALPHA, a shock-capturing code employing a high-order Godunov scheme to track large density variations...[Show more]
