Neutron star composition in strong magnetic fields
نویسنده
چکیده
We study the problem of neutron star composition in the presence of a strong magnetic field. The effects of the anomalous magnetic moments of both nucleons and electrons are investigated in relativistic mean field calculations for a β-equilibrium system. Since neutrons are fully spin polarized in a large field, generally speaking, the proton fraction can never exceed the field free case. An extremely strong magnetic field may lead to a pure neutron matter instead of a proton-rich matter. PACS number(s): 26.60.+c; 97.10.Ld; 97.60.Jd

Neutron star matter in the quark-meson coupling model in strong magnetic fields
P. Yue and H. Shen Department of Physics, Nankai University, Tianjin 300071, China Abstract The effects of strong magnetic fields on neutron star matter are investigated in the quark-meson coupling (QMC) model. The QMC model describes a nuclear many-body system as nonoverlapping MIT bags in which quarks interact through self-consistent exchange of scalar and vector mesons in the mean-field appr...
متن کاملMatter and Radiation in Superstrong Magnetic Fields and Thermal Emission from Neutron Stars
Thermal surface emissions have now been detected from more than a dozen isolated neutron stars, including radio pulsars, radioquiet neutron stars and magnetars. These detections can potentially provide important information on the interior physics, magnetic fields, and surface composition of neutron stars. Understanding the properties of matter and radiative transfer in strong magnetic fields i...
متن کاملEffect of Isovector-scalar Meson on Neutron Star Matter in Strong Magnetic Fields
We study the effects of isovector-scalar meson δ on the equation of state (EOS) of neutron star matter in strong magnetic fields. The EOS of neutron-star matter and nucleon effective masses are calculated in the framework of Lagrangian field theory, which is solved within the mean-field approximation. From the numerical results one can find that the δ-field leads to a remarkable splitting of pr...

I briefly review some aspects of the effect of magnetic fields in the high density regime relevant to neutron stars, focusing mainly on compact star structure and composition, superconductivity, combustion processes, and gamma ray bursts. THE “MAGNETIC FIELD” OF “NEUTRON STARS” A large body of evidence now identifies the presence of strong magnetic fields at (or very near) the surface of neutro...
متن کاملNon-Relativistic Limit of Neutron Beta-Decay Cross-Section in the Presence of Strong Magnetic Field
One of the most important reactions of the URCA that lead to the cooling of a neutron star, is neutron beta-decay ( ). In this research, the energy spectra and wave functions of massive fermions taking into account the Anomalous Magnetic Moment (AMM) in the presence of a strong changed magnetic field are calculated. For this purpose, the Dirac-Pauli equation for charged and neutral fermions is ...
