The Role of trapped neutrino in dense stellar matter and kaon condensation

چکیده

We investigate the effect of neutrino trapping on the kaon condensation process and Equation of State (EOS) in a newly formed neutron star matter which is less than several seconds old. Using nonlinear relativistic mean field model ,we find that the presence of neutrino shifts the threshold density for kaon condensation and muon production to much higher density. We also studied the pressure and energy density of the system and found that the presence of neutrino stiffens the EOS which may be responsible for the delayed exploision mechanism for supernovae.

Microscopic three-body forces and kaon condensation in cold neutrino-trapped matter

We investigate the composition and the equation of state of the kaon condensed phase in neutrinofree and neutrino-trapped star matter within the framework of the Brueckner-Hartree-Fock approach with three-body forces. We find that neutrino trapping shifts the onset density of kaon condensation to a larger baryon density, and reduces considerably the kaon abundance. As a consequence, when kaons ...

Evolution of Proto–neutron Stars with Kaon Condensates

We present simulations of the evolution of a proto-neutron star in which kaon-condensed matter might exist, including the effects of finite temperature and trapped neutrinos. The phase transition from pure nucleonic matter to the kaon condensate phase is described using Gibbs’ rules for phase equilibrium, which permit the existence of a mixed phase. A general property of neutron stars containin...

Dependence of relative abundances of constituents in dense stellar matter on nuclear symmetry energy

For a dense stellar matter, which is electrically neutral and in beta equilibrium, the electron chemical potential, μe, will depend nontrivially on baryonic matter density. It is generally expected that as density increases, the electron chemical potential will increase and new degrees of freedom will emerge as μe becomes comparable to their energy scales. Assuming the electrical neutrality and...

Kaon Energies in Dense

We discuss the role of kaon-nucleon and nucleon-nucleon correlations in kaon condensation in dense matter. Correlations raise the threshold density for kaon condensation, possibly to densities higher than those encountered in stable neutron stars.
