Materia extraña en el universo

Resumen en español La hipótesis de la materia de quarks extraña constituye una de las especulaciones más excitantes de la Física del siglo XX. Si dicha hipótesis fuese correcta, la materia de quarks constituiría el estado más fundamental de la materia, conformaría el nucleo de objetos compactos como las estrellas de neutrones y podría formar objetos aun más exóticos como las estrellas de quarks. Debido al régimen de alta densidad y baja temperatura al que se encuentran sometidas (mas) estas estrellas es posible que la interacción atractiva de los quarks, a través del intercambio de gluones, favorezca la aparición de una fase superconductora de color, modificando significativamente la ecuación de estado del sistema. En este trabajo se pretende dar un panorama general de esta tematica, teniendo en cuenta, además, la influencia de campos magnéticos intensos en las estrellas de quarks Resumen en inglés The strange quark matter hypothesis is one of the most exciting speculations of the XX Century Physics. If this hypothesis is correct, the ground state of the matter would be the strange matter, which could form the core of compact objects like neutron stars or even more exotic objects like quarks stars. Due to the high-density and low-temperature regime in these stars, the interaction between quarks through gluon exchange could favor the appearance of a color superconduc (mas) ting state, significantl modifying the equation of state of the system. In this paper we present a general overview of this subject, taking also into account the effect of strong magnetic field in the quark stars
