The physics of neutron stars

  title={The physics of neutron stars},
  author={Alexander Y. Potekhin},
Topical problems in the physics of and basic facts about neutron stars are reviewed. The observational manifestations of neutron stars, their core and envelope structure, magnetic fields, thermal evolution, and masses and radii are briefly discussed, along with the underlying microphysics.

Nuclear Physics of the Outer Layers of Accreting Neutron Stars.
Now 50 years since the existence of the neutron star crust was proposed, we review the current understanding of the nuclear physics of the outer layers of accreting neutron stars. Nuclei producedExpand
Spin down of rotating compact magnetized strange stars in general relativity
We find that in general relativity slow down of the pulsar rotation due to the magnetodipolar radiation is more faster for the strange star with comparison to that for the ordinary neutron star ofExpand
Connection of Additional Pulsar Emission Components in the Crab with the Resonance Reflection from a Neutron Star
Additional high-frequency components of the pulsar radiation in Crab Nebula are considered as a result of the resonance with the surface electromagnetic wave at nonlinear reflection from of theExpand
Effect of the neutron lifetime on processes in the early universe
The influence of the neutron lifetime on the abundance of light elements produced during the primordial nucleosynthesis early in the birth of the Universe is considered. Among light elements, namely,Expand
Significance of lower energy density region of neutron star and universalities among neutron star properties
We have constructed and compared models of rotating neutron stars and strange stars, within the Hartle framework. The significance of the low energy density region and crust region inside the neutronExpand
Atmospheres and radiating surfaces of neutron stars
The early 21st century witnesses a dramatic rise in the study of thermal radiation of neutron stars. Modern space telescopes have provided a wealth of valuable information which, when properlyExpand

A model equation of state that describes the phase transition to quark matter is proposed. This equation of state is used to construct hydrostatically equilibrium stellar models for various values ofExpand
Nuclear Transformations Under Strong Compression
This chapter is dedicated to the consideration of the most “extreme states” of matter: neutron and nuclear matter. This state of matter is hardly attainable for terrestrial laboratories and thereforeExpand
Plasma magnetosphere and spin down of rotating magnetized strange stars in general relativity

Maser Emission from Gravitational States on Isolated Neutron Stars
Despite years of research on neutron stars, the source of their radio emission is still under debate. Here we propose a new coherent mechanism of pulsar radio emission based on transitions betweenExpand

Theory of cooling neutron stars versus observations
We review current state of neutron star cooling theory and discuss the prospects to constrain the equation of state, neutrino emission and superfluid properties of neutron star cores by comparing theExpand
Kaon Condensation in Neutron Stars
We discuss the kaon-nucleon interaction and its consequences for the change of the properties of the kaon in the medium. The onset of kaon condensation in neutron stars under various scenarios asExpand

Abstract Recent equations of state for dense nuclear matter are discussed with possible phase transitions arising in neutron stars such as pion, kaon and hyperon condensation, superfluidity and quarkExpand
Rotating Neutron Stars as the Origin of the Pulsating Radio Sources
The constancy of frequency in the recently discovered pulsed radio sources can be accounted for by the rotation of a neutron star. Because of the strong magnetic fields and high rotation speeds,Expand
Liquid Crystals in the Mantles of Neutron Stars
Recent calculations indicate that in the outer parts of neutron stars nuclei are rod-like or slab-like, rather than roughly spherical. We consider the elastic properties of these phases, and argueExpand
The relativistic equations of stellar structure and evolution. Stars with degenerate neutron cores. 1: Structure of equilibrium models
The general relativistic equations of stellar structure and evolution are reformulated in a notation which makes easy contact with Newtonian theory. Also, a general relativistic version of theExpand
