Title in Portuguese
Gluons em estrelas de nêutrons
Keywords in Portuguese
Equação de estado para QGP frio
Estudo de Nêutrons
Abstract in Portuguese
O plasma de quarks e gluons (QGP) em temperatura zero e alta densidade bariônica é um sistema que pode existir no interior de estrelas densas. É possível que esse QGP frio compartilhe algumas características com o plasma quente, observado em colisões de íons pesados relativísticos, sendo também um sistema fortemente interagente. Neste trabalho, utilizamos uma equação de estado derivada a partir da QCD e a aplicamos no estudo de estrutura estelar. Mostramos que nossos resultados são compatíveis com o pulsar PSR J1614 2230 de massa (1.97 ± 0.04)M.

Neutron Stars Equation for the cold QGP
Abstract in English
The Quark Gluon Plasma (QGP) at zero temperature and high baryon number is a system that may exist in the core of dense stars. This cold QGP has a rich phase structure and at high enough chemical potential it is quite possible that it shares some features with the hot QGP observed in heavy ion collisions, being also a strongly interacting system. We use an equation of state derived from QCD and apply it to study of stellar structure. Our results reproduce the measured mass, (1.97 ± 0.04)M, of the pulsar PSR J1614 2230.
