TLDR
In this article, the influence of strong magnetic fields on the properties and internal structure of these strongly magnetized neutron stars (magnetars) was investigated and it was shown that the presence of a sufficiently strong magnetic field changes the ratio of protons to neutrons as well as the neutron drip density.
Abstract
Neutron stars with very strong surface magnetic fields have been suggested as the site for the origin of observed soft gamma repeaters (SGRs). In this paper we investigate the influence of such strong magnetic fields on the properties and internal structure of these strongly magnetized neutron stars (magnetars). We study properties of a degenerate equilibrium ideal neutron-proton-electron (npe) gas with and without the effects of the anomalous nucleon magnetic moment in a strong magnetic field. The presence of a sufficiently strong magnetic field changes the ratio of protons to neutrons as well as the neutron drip density. We also study the appearance of muons as well as pion condensation in strong magnetic fields. We discuss the possibility that boson condensation in the interior of magnetars might be a source of SGRs.

Neutron Stars—Cooling and Transport

TL;DR: In this paper, the basics of thermal evolution for isolated neutron stars with strong magnetic fields are reviewed, including most relevant thermodynamic and kinetic properties in the stellar core, crust, and blanketing envelopes.

Thermal structure and cooling of neutron stars with magnetized envelopes

TL;DR: In this article, the thermal structure of neutron stars with magnetized envelopes is studied using modern physics input and the relation between the internal (Tint) and local surface temperatures is calculated and tted by analytic expressions for magnetic eld strengths B from 0 to 10 16 G and arbitrary inclination of the eld lines to the surface.

Color-flavor locked superconductor in a magnetic field

TL;DR: In this paper, the effects of moderately strong magnetic fields on the properties of color-flavor locked quark matter were studied in the framework of the Nambu-Jona-Lasinio model.

Equation of state for nucleonic and hyperonic neutron stars with mass and radius constraints

TL;DR: In this article, a new equation of state for the nucleonic and hyperonic inner core of neutron stars is obtained from a new parametrization of the FSU2 relativistic mean field functional that satisfies these latest astrophysical constraints and reproduces the properties of nuclear matter and finite nuclei while fulfilling the restrictions on high-density matter deduced from heavy-ion collisions.

Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor

TL;DR: A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled and exhibited a nonthermal, anisotropic velocity distribution expected of the minimum-energy quantum state of the magnetic trap in contrast to the isotropic, thermal velocity distribution observed in the broad uncondensed fraction.

Formation of very strongly magnetized neutron stars - Implications for gamma-ray bursts

TL;DR: In this article, it is argued that a convective dynamo can also generate a very strong dipole field after the merger of a neutron star binary, but only if the merged star survives for as long as about 10-100 ms.

Observation of a Rapidly Pulsating Radio Source

TL;DR: In this article, the first report of a curious class of astronomical radio sources, distinguished by their rapid and extremely regular pulsations, was made by Hewish et al. They are now understood to be rapidly rotating, magnetized neutron stars, or pulsars.
