Role of nonlinear vector meson interactions in hyperon stars
Ilona Bednarek, Ryszard Manka
The extended nonlinear model has been applied to construct neutron star matter equation of state. In the case of neutron star matter with non-zero strangeness the extension of the…
The hyperon neutron star mean field model
Ilona Bednarek, Ryszard Manka
In this paper the impact of the strength of hyperon-nucleon and hyperon-hyperon on the maximum neutron star mass is shown. The strong hyperon-hyperon coupling constant together wit…
The compact star in the SU(3) sigma model
Ryszard Manka, Ilona Bednarek
The linear chiral SU(3)*SU(3) model is applied to describe properties of the compact star matter inside the quark, protoneutron and neutron star.The leads to the neutron star with…
Properties and evolution of a protoneutron star in the enlarged SU(3) model
Ilona Bednarek, Marcin Keska, Ryszard Manka
Protoneutron stars are hot and lepton rich objects formed as a result of type II supernovae explosion. This paper describes results of analysis of protoneutron star models construc…
The extended, relativistic hyperon star model
I. Bednarek, M. Keska, R. Manka
In this paper an equation of state of neutron star matter which includes strange baryons in the framework of Zimanyi and Moszkowski (ZM) model has been obtained. We concentrate on…
The influence of asymmetry on a magnetized proto-neutron star
I. Bednarek, A. Brzezina, R. Manka +1
Using the Relativistic Mean Field Theory (RMF) it is shown that different proton fraction which is directly connected with the neutron excess and with the asymmetry of the system a…
