Dynamical stability of collisionless stellar systems and barotropic stars: the nonlinear Antonov first law


We complete previous investigations on the dynamical stability of barotropic stars and collisionless stellar systems. A barotropic star that minimizes the energy functional at fixed mass is a nonlinearly dynamically stable stationary solution of the Euler-Poisson system. Formally, this minimization problem is similar to a condition of “canonical stability… (More)
