A model for giant flares in soft gamma repeaters
G. Lugones, E. M. de Gouveia Dal Pino, J. E. Horvath
We argue that giant flares in SGRs can be associated to the core conversion of an isolated neutron star having a subcritical magnetic field G and a fallback disk aro…
Constraints on superdense preon stars and their formation scenarios
J. E. Horvath
We address in this work the general features of a possible compact stars composed by elementary fermions beyond the quark level. The {\it locus} of these hypothetic objects in the…
Another Decade of Strange Quark Matter (ASTRO) Physics
J. E. Horvath, G. Lugones
We present a perspective of strange quark matter research in the 1991-2001 decade focused on astrophysics topics, with particular attention to open problems. We outline the basic c…
On gamma-ray bursts and their biological effects :a case for an extrinsic trigger of the Cambrian explosion ?
J. E. Horvath
We discuss some the effects of local gamma-ray bursts on the earth's atmosphere. A rough calculation of the fraction of ozone destruction by catalytic cycles is given, whi…
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…
Diquark degrees of freedom in the EOS and the compactness of compact stars
J. E. Horvath, G. Lugones, J. A. de Freitas Pacheco
We discuss the role of diquarks in constructing models of compact stars. These approaches are compared to recent claims of highly compact X-ray and isolated sources.
