Neutron Stars as a Probe for Dense Matter
V. Dexheimer, S. Schramm
We study different stages of the neutron star cooling by computing neutron star properties at various temperatures and entropies using an effective chiral model including hadronic…
Proto-Neutron and Neutron Stars in a Chiral SU(3) Model
V. Dexheimer, S. Schramm
A hadronic chiral SU(3) model is applied to neutron and proto-neutron stars, taking into account trapped neutrinos, finite temperature and entropy. The transition to the chirally r…
Parity Doublet Model applied to Neutron Stars
V. Dexheimer, S. Schramm, H. Stoecker
The Parity doublet model containing the SU(2) multiplets including the baryons identified as the chiral partners of the nucleons is applied for neutron star matter. The chiral rest…
Neutron Stars in a Chiral Model with Finite Temperature
V. Dexheimer, S. Schramm, H. Stoecker
Neutron star matter is investigated in a hadronic chiral model approach using the lowest flavor-SU(3) multiplets for baryons and mesons. The parameters are determined to yield cons…
On the Density Dependent Nuclear Matter Compressibility
V. A. Dexheimer, C. A. Z. Vasconcellos, B. E. J. Bodmann
In the present work we apply a quantum hadrodynamic effective model in the mean-field approximation to the description of neutron stars. We consider an adjustable derivative-coupli…
