Materia densa y perturbaciones relativistas no radiales en protoestrellas de quarks
Abstract
Depending on temperature, T, and chemical potential, $\mu$, quark matter in the Universe may appear in two regimes: cosmological and astrophysical. We focus, particularly, in the astrophysical regime (equivalent to consider $T \ll \mu $). These are the conditions of the matter present in the interior of neutron stars and/or hypothetical quark stars. In this work, using a simple phenomenological model as the MIT Bag Model to describe the matter, we present results --such as Mass-Radius relationships and non radial oscillations frequencies of protoquark stars-- satisfying some of the restrictions established for the astrophysics of compact objects, considering different stages of their evolution.
