Formação de ressonâncias delta em estrelas de nêutron com a mudança das constantes de acoplamento híperon-méson / Formation of delta resonances in neutron stars with changing of the hyperon-meson coupling constants

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / No presente trabalho investigamos os efeitos da mudança das constantes de acoplamento entre os híperons (D; L; S e X) e os mésons (s; w e r) tendo em vista sua aplicacação na estrutura de estrelas de nêutron. Para tanto, adotamos o modelo de Walecka não-linear numa aproximacão de campo médio. / In the present work we investigated the effects of changing of the coupling constants between the hyperons (D; L; S and X) and mesons (s; w and r) regarding its application in the structure of neutron stars. To this end, we adopted the non-linear Walecka model in the mean field approximation.
