▪ Abstract Turbulence affects the structure and motions of nearly all temperature and density
regimes in the interstellar gas. This two-part review summarizes the observations, theory …

We discuss the nature of phase transitions in self-gravitating systems. We show the
connection between the binary star model of Padmanabhan, the thermodynamics of stellar …

We provide an approximate analytical expression of the mass-radius relation of a Newtonian
self-gravitating Bose-Einstein condensate (BEC) with short-range interactions described by …

We review what has been learned recently using N-body simulations about the evolution of
globular clusters. While simulations of star clusters have become more realistic, and now …

The instability of fluid flows is a key topic in classical fluid mechanics because it has huge
repercussions for applied disciplines such as chemical engineering, hydraulics, aeronautics …

This memoir focuses on $ Lp $ estimates for objects associated to elliptic operators in
divergence form: its semigroup, the gradient of the semigroup, functional calculus, square …

The origin of the empirical laws of galactic scale star formation is considered in view of the
self-similar nature of interstellar gas and the observation that most local clusters are …

We analyze the possibility that due to their superfluid properties some compact astrophysical
objects may contain a significant part of their matter in the form of a Bose-Einstein …

We introduce a class of generalized Fokker-Planck equations that conserve energy and
mass and increase a generalized entropy functional until a maximum entropy state is …

We study the thermodynamics and the collapse of a self-gravitating gas of Brownian
particles. We consider a high-friction limit in order to simplify the problem. This results in the …
