In this article, different stages of magnetized quark star evolution incorporating baryon number conservation and using an anisotropic energy momentum tensor were analyzed, and the first stages of the evolution were simulated through the inclusion of trapped neutrinos and fixed entropy per particle, while in the last stage the star was taken to be deleptonized and cold.Abstract:
We analyze different stages of magnetized quark star evolution incorporating baryon number conservation and using an anisotropic energy momentum tensor. The first stages of the evolution are simulated through the inclusion of trapped neutrinos and fixed entropy per particle, while in the last stage the star is taken to be deleptonized and cold. We find that, although strong magnetic fields modify quark star masses, the evolution of isolated stars needs to be constrained by fixed baryon number, which necessarily lowers the possible star masses. Moreover, magnetic field effects, measured by the difference between the parallel and perpendicular pressures, are more pronounced in the beginning of the star evolution, when there is a larger number of charged leptons and up quarks. We also show that having a spatially varying magnetic field allows for larger magnetic fields to be supported.read more

Consistent neutron star models with magnetic-field-dependent equations of state
TL;DR: In this paper, a self-consistent model for the study of the structure of a neutron star in strong magnetic fields is presented, which includes the effect of the magnetic field on the equation of state, the interaction of the electromagnetic field with matter, and anisotropies in the energy-momentum tensor, as well as general relativistic aspects.

TL;DR: In this article, the effect of the magnetic field on the mass and shape of a star was studied and the excess mass and change in the equatorial radius of the star due to the non-uniform magnetic field was found to be about 3-4% compared to the spherical solution.

Magnetic susceptibility of a neutron star crust.
R. D. Blandford,L. Hernquist +1 more
TL;DR: The magnetic susceptibility of the degenerate free electrons in the crust of a neutron star is computed for a range of densities, temperatures, and field strengths as discussed by the authors, and it is shown that when the temperature is low enough (typically less than 107K for densities of about 107 g cm-3 and 1012 G fields), the susceptibility undergoes large de Haas-van Alphen oscillations.

Color superconductivity in a strong external magnetic field
TL;DR: In this article, the effects of an applied strong external magnetic field in a three flavor massless color superconductor were explored, where the long-range component of the B field that penetrates the super-conductor enhances some quark condensates, leading to a different condensation pattern.

Pasta Structures of Quark-Hadron Phase Transition in Proto-Neutron Stars
TL;DR: In this article, the quark-hadron mixed phase in proto-neutron stars with the finite-size effects was studied and it was shown that the region of the mixed phase is limited due to thermal instability.

TL;DR: The observed correlations between the characteristic ages and dipole surface magnetic field strengths of all pulsars can be well explained by magnetic field decay with core temperatures of $~2\times10^{8}$ K, $sim2/times10/7$ K and $sim10/5$ K for magnetars, normal radio pulsars, and millisecond pulsars as mentioned in this paper.
