A self-gravitating system composed of baryonic and dark matter analysed from the post-Newtonian Boltzmann equations

Gilberto M. Kremer, Kamel Ourabah

We study the Jeans gravitational instability for a mixture of baryonic and dark matter particles, in the post-Newtonian approximation. We adopt a kinetic model consisting of a coup…

Relaxation-Time Model for the Post-Newtonian Boltzmann Equation

Gilberto M. Kremer

The non-equilibrium contributions to the post-Newtonian hydrodynamic equations are determined from a relaxation-time model of the post-Newtonian Boltzmann equation. The Chapman-Ens…

Stellar structure model in the post-Newtonian approximation

Gilberto Medeiros Kremer

In this work the influence of the post-Newtonian corrections to the equations of stellar structure is analysed. The post-Newtonian Lane-Emden equation follows from the correspondin…

Post-Newtonian Jeans Equation for Stationary and Spherically Symmetrical Self-Gravitating System

Gilberto M. Kremer

The post-Newtonian Jeans equation for stationary self-gravitating systems is derived from the post-Newtonian Boltzmann equation in spherical coordinates. The Jeans equation is coup…

Granular gas of inelastic and rough Maxwell particles

Gilberto M. Kremer, Andrés Santos

The most widely used model for granular gases is perhaps the inelastic hard-sphere model (IHSM), where the grains are assumed to be perfectly smooth spheres colliding with a consta…

Post-Newtonian non-equilibrium kinetic theory

Gilberto M. Kremer

The post-Newtonian hydrodynamic equations for a non-perfect fluid are developed within the framework of a post-Newtonian Boltzmann equation. The post-Newtonian components of the en…
