- Description
- Neutrino trapping effects on the properties of dense stellar mater in nonstrange supranuclear regime are studied with the purpose of applying to supernovae dynamical evolution. The hadronic and leptonic compositions of stellar matter are solved in the context of the relativistic mean-field theory coupled with the <math>\beta\!\,</math>-equilibrium condition, and maintaining the charge neutrality of the stellar medium. It is shown that the matter composition depends dramatically on the confined electronic-leptonic fraction. However, the values of the isoscalar fields are almost insensitive to variations of that quantity. The softness of the equation of state and the lowering of the nuclear incompressibility values, with respect to the situation in which neutrino confinement is not considered, are the remarkable results.
