Anisotropic dark energy stars
Cristian R. Ghezzi
A model of compact object coupled to inhomogeneous anisotropic dark energy is studied. It is assumed a variable dark energy that suffers a phase transition at a critical density. T…
Relativistic Structure, Stability and Gravitational Collapse of Charged Neutron Stars
Cristian R. Ghezzi
Charged stars have the potential of becoming charged black holes or even naked singularities. It is presented a set of numerical solutions of the Tolman-Oppenheimer-Volkov equation…
Numeric simulation of relativistic stellar core collapse and the formation of Reissner-Nordstrom space-times
Cristian R. Ghezzi, Patricio S. Letelier
The time evolution of a set of 22 Mo unstable charged stars that collapse is computed integrating the Einstein-Maxwell equations. The model simulate the collapse of an spherical st…
Numerical Simulation of General Relativistic Stellar Collapse
Cristian R. Ghezzi, Patricio S. Letelier
We present preliminar results and tests of a new general relativistic code to simulate the hydrodynamic collapse of a 21 solar masses star. We have assumed spherical symmetry and u…
Asymmetric Explosions of Thermonuclear Supernovae
C. R. Ghezzi, E. M. de Gouveia Dal Pino, J. E. Horvath
A type Ia supernova explosion starts in a white dwarf as a laminar deflagration at the center of the star and soon several hydrodynamic instabilities (in particular, the Rayleigh-T…
Asymmetric Explosions of Type Ia Supernovae
Cristian R. Ghezzi, E. M. de Gouveia Dal Pino, Jorge E. Horvath
The burning speed of a thermonuclear supernova front could be described by the fractal model of combustion. We have examined the effects of magnetic fields on the fractalization of…
