Title: Density distribution function of a self-gravitating isothermal compressible turbulent fluid in the context of Molecular Clouds ensembles Keywords: methods: statistical – ISM: clouds – ISM: structure Abstract: We have set ourselves the task of obtaining the probability distribution function of the mass density of a self-gravitating isothermal compressible turbulent fluid from its physics.We have done this in the context of a new notion: the molecular clouds ensemble.We have applied a new approach that takes into account the fractal nature of the fluid. Using the medium equations,under the assumption of steady state, we show that the total energy per unit mass is an invariant with respect to the fractal scales. As a next step we obtain a non-linear integral equation for the dimensionless scale Q which is the third root of the integral of the probability distribution function. It is solved approximately up to the leading-order term in the series expansion. We obtain two solutions. References Issue
