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…
Effects of the magnetic fields on the protoneutron star structure
R. Manka, M. Zastawny-Kubica, A. Brzezina +1
The equation of state of a protoneutron star matter including the effects of magnetic field, temperature, nuclear asymmetry and trapped neutrinos are studied. Using the Oppenheimer…
Effects of the magnetic fields on the helium white dwarfs structure
R. Manka, M. Zastawny-Kubica, A. Brzezina +1
In this paper the effect of the magnetic field on the form of the equation of state and helium white dwarfs structure are discussed. The influence of the temperature and magnetic f…
QCD deconfinement -- phase transitions and collapsing quark stars
Ilona Bednarek, Marek Biesiada, Ryszard Manka
In this paper we discuss the QCD phase-transitions in the nontopological soliton model of quark confinement and explore possible astrophysical consequences. Our key idea is to look…
