Boson-fermion stars: going to larger boson masses

We reexamine some of the properties of the boson-fermion stars, in particular the transition from boson-dominated to fermion-dominated configurations as a function of the fermion and boson densities at the origin. The limit of large boson masses ( m⪢10 −11 eV) is also investigated, in which case we...

Description
Summary:We reexamine some of the properties of the boson-fermion stars, in particular the transition from boson-dominated to fermion-dominated configurations as a function of the fermion and boson densities at the origin. The limit of large boson masses ( m⪢10 −11 eV) is also investigated, in which case we find that the eigenvalue characterizing the equations and the transition point mentioned above become largely independent of the mass of the bosons.
