A Polytropic Approach to Semi-relativistic Isothermal Gas Spheres at Arbitrary Temperature

Claudio M. G. de Sousa, Evandro A. de Araujo

We use standard polynomial expansion technique to show the existence of a relation between polytropic model and the description of gas spheres at finite temperature. A numerical an…

Rotating Boson and Boson-Fermion Stars

Claudio M. G. de Sousa

Some recent results on rotating self-gravitating configurations composed with Bosons and Fermions are reported. Given a star composed of both Bosons and Fermions without interactio…

On the frequency shift of gravitational waves

Claudio M. G. de Sousa

Considering plane gravitational waves propagating through flat spacetime, it is shown that curvatures experienced both in the starting point and during their arrival at the earth c…

Slowly Rotating Boson Fermion Stars

Claudio M G de Sousa, Vanda Silveira

Relativistic prescription is used to study the slow rotation of stars composed by self-gravitating bosons and fermions (fermions may be considered as neutrons). Previous results de…

Boson Star Rotation: A Newtonian Approximation

Vanda Silveira, Claudio M. G. de Sousa

Using the Newtonian approximation, we study rotating compact bosonic objects. The equations which describe stationary states with non-zero angular momentum are constructed and some…

A Model for Stars of Interacting Bosons and Fermions

Claudio M. G. de Sousa, J. L. Tomazelli

In this paper we introduce a current-current type interaction term in the Lagrangian density of gravity coupled to complex scalar fields, in the presence of a degenerated Fermi gas…
