Model Interacting Boson-Fermion Stars
Claudio M. G. de Sousa, J. L. Tomazelli, Vanda Silveira
This report gives an outline of current-current type interaction between self-gravitating bosons and fermions.
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…
Topologica Defects and Corrections to the Nambu Action
Vanda Silveira, M. D. Maia
The effective action of a (1+2)-dimensional defect is obtained as an expansion in powers of the thickness.Considering non-straight solutions as the zero order term, the corrections…
