Self-similar growth of Bose stars [CEA]

http://arxiv.org/abs/2305.01005


We analytically solve the problem of Bose star growth in the bath of gravitationally interacting particles. We find that after nucleation of this object, the bath is described by a self-similar solution of the kinetic equation, which is an attractor. Together with the conservation laws, this fixes mass evolution of the Bose star. Our results explain slowdown of the star growth at a certain “core-halo” mass, but also predict formation of the heavier and lighter objects in magistral dark matter models.
