Aims. We calculate the energy release associated with a strong first-order phase transition, from normal phase N to an “exotic” superdense phase S, in a rotating neutron star. Such a phase transition N −→ S, accompanied by a density jump ρ N −→ ρ S ,i s characterized by ρS /ρN > 3 (1 + P0/ρNc 2 ), where P0 is the pressure at which phase transition occurs. Configurations with small S-phase cores are then unstable and collapse into stars with large S-phase cores. The energy release is equal to… 

Consequences of a strong phase transition in the dense matter equation of state for the rotational evolution of neutron stars

We explore the implications of a strong first-order phase transition region in the dense matter equation of state in the interiors of rotating neutron stars, and the resulting creation of two

Phase Transition Effects on the Dynamical Stability of Hybrid Neutron Stars

We study radial oscillations of hybrid nonrotating neutron stars composed by a quark matter core and hadronic external layers. At first, we physically deduce the junction conditions that should be

Relativistic hybrid stars with super-strong toroidal magnetic fields: An evolutionary track with QCD phase transition

ABSTRACT We investigate structures of hybrid stars, which feature quark core surrounded bya hadronic matter mantle, with super-strong toroidal magnetic fields in full generalrelativity. Modeling the

Differentiating sharp phase transitions from mixed states in neutron stars

The internal composition of neutron stars is still an open issue in astrophysics. Their innermost regions are impervious to light propagation and gravitational waves mostly carry global aspects of

Effects of the quark-hadron phase transition on highly magnetized neutron stars

The presence of quark-hadron phase transitions in neutron stars can be related to several interesting phenomena. In particular, previous calculations have shown that fast rotating neutron stars, when

Rotating neutron stars with exotic cores: masses, radii, stability

Abstract.A set of theoretical mass-radius relations for rigidly rotating neutron stars with exotic cores, obtained in various theories of dense matter, is reviewed. Two basic observational

Probing Elastic Quark Phases in Hybrid Stars with Radius Measurements

The internal composition of neutron stars is currently largely unknown. Due to the possibility of phase transitions in quantum chromodynamics, stars could be hybrid and have quark cores. We

Spectral Methods for Numerical Relativity

This paper focuses on a class called spectral methods in which, typically, the various functions are expanded in sets of orthogonal polynomials or functions, and presents results obtained by various groups in the field of general relativity by means of spectral methods.

An introduction to the theory of rotating relativistic stars

These lecture notes are intended to introduce the theory of rotating stars in general relativity. The focus is put on the theoretical foundations, with a detailed discussion of the spacetime

Energy release associated with a first-order phase transition in a rotating neutron star core

Aims. We calculate energy release associated with a first order phase transition at the center of a rotating neutron star. This quantity is equal to the difference in mass-energies between the

Phase transitions in rotating neutron stars cores: back bending, stability, corequakes, and pulsar timing

Aims. We analyze potentially observable phenomena during spin evolution of isolated pulsars, such as back bending and corequakes resulting from instabilities, which could result from phase

We present approximate formulae describing the changes in neutron-star parameters caused by the first-order phase transition to an exotic state (pion or kaon condensate, quark matter) resulting in
