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…
