Superfluid phase transitions in dense neutron matter.
The phase transitions in a realistic system with triplet pairing, dense neutron matter, have been investigated. The spectrum of phases of the 3P2-3F2 model, which adequately describes pairing in this system, is analytically constructed with the aid of a separation method for solving BCS gap equations in states of arbitrary angular momentum. In addition to solutions involving a single value of t...
متن کاملPhase Transitions in Dense Matter and Recent Topics of Neutron Stars
Core of neutron star consists of highly dense matter above normal nuclear density ρ0 ≃ 0.16fm , where phase transitions is expected to take place. We review some phase transitions and recent topics of neutron stars. INTRODUCTION There exist many candidates of the phase transitions in highly dense nuclear matter: boson condensation (K,π), quark matter, hyperonic matter and so on [1]. They are of...
متن کاملPhase Transitions in Neutron Stars and Maximum Masses.
Using the most recent realistic effective interactions for nuclear matter with a smooth extrapolation to high densities including causality, we constrain the equation of state and calculate maximum masses of rotating neutron stars. First- and second-order phase transitions to, e.g., quark matter at high densities are included. If neutron star masses of approximately 2.3 M middle dot in circle f...
متن کاملEquation of State of Dense Matter and Maximum Mass of Neutron Stars
Theoretical models of the equation of state (EOS) of neutronstar matter (starting with the crust and ending at the densest region of the stellar core) are reviewed. Apart from a broad set of baryonic EOSs, strange quark matter, and even more exotic (abnormal and Q-matter) EOSs are considered. Results of calculations of Mmax for non-rotating neutron stars and exotic compact stars are reviewed, w...
متن کاملPhases of Dense Matter in Neutron Stars
After a brief history of neutron stars and supernovae recent developments are discussed. Based on modern nucleon-nucleon potentials more reliable equations of state for dense nuclear matter have been constructed. Furthermore, phase transitions such as pion, kaon and hyperon condensation, superfluidity and quark matter can occur in cores of neutron stars. Specifically, the nuclear to quark matte...
