Gravitational stability of cold Bose star

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The maximum mass of cold Bose star that can sustain its own gravity is determined to be ≈0.6/Gm, wherem is the mass of boson. This is different from the Oppenheimer-Volkoff mass of ≈0.4/G 3/2 m 2 N for the neutron star and may facilitate formation of smaller black holes made of cold invisible axions in the axion dominated universe.
