Abstract

We consider star models consisting of spin 0 particles interacting only gravitationally, e.g. Higgs-particles as possible dark matter objects. The particle gas of finite temperature is treated according to the Bose-Einstein-statistics in its non- relativistic limit; then the use of Newtonian gravity is sufficient too. The limits of these restrictions are estimated. The local temperature is determined with the use of energy conservation. The mass-radius relation of the objects and their further behaviours as Bose-Einstein-condensation in the outer regions are calculated. We find strong similarities with the features of white dwarfs and neutron stars.
