Conformally flat polytropes for anisotropic matter
L. Herrera, A. Di Prisco, W. Barreto +1
We analyze in detail conformally flat spherically symmetric fluid distributions, satisfying a polytropic equation of state. Among the two possible families of relativistic polytrop…
General relativistic polytropes for anisotropic matter: The general formalism and applications
L. Herrera, W. Barreto
We set up in detail the general formalism to model polytropic general relativistic stars with anisotropic pressure. We shall consider two different possible polytropic equations, a…
Newtonian polytropes for anisotropic matter: General framework and applications
L. Herrera, W. Barreto
We set up the general formalism to model polytropic Newtonian stars with anisotropic pressure. We obtain the corresponding Lane-Emden equation. A heuristic model based on an ansatz…
Electromagnetic radiation produces frame dragging
L. Herrera, W. Barreto
It is shown that for a generic electrovacuum spacetime, electromagnetic radiation produces vorticity of worldlines of observers in a Bondi--Sachs frame. Such an effect (and the ens…
Evolution of relativistic polytropes in the post--quasi--static regime
L. Herrera, W. Barreto
A recently presented method for the study of evolving self-gravitating relativistic spheres is applied to the description of the evolution of relativistic polytropes. Two different…
