Energy Release Due to Antineutrino Untrapping from Hot Quark Stars
نویسنده
چکیده
An equation of state for 2-flavor quark matter (QM) with diquark condensation under the conditions for compact stars -β-equilibrium, charge and color neutralityis presented. Trapped antineutrinos prevent the formation of the diquark condensate at moderate densities above a critical value of the antineutrino chemical potential μcν̄e . The following consequences are presented: 1) The star develops a 2-phase structure (μν̄e ≥ μ c ν̄e ): a color superconducting QM core and a normal QM shell. 2)During the cooling, when the temperature is small enough (T < 1 MeV) the antineutrino mean free path becomes larger than the thickness of the normal QM shell and the antineutrinos get untrapped in a sudden burst. The energy release is estimated as ≃ 10 erg and an antineutrino pulse is expected to be observed.

Energy release due to antineutrino untrapping and diquark condensation in hot quark star evolution
We study the consequences of antineutrino trapping in hot quark matter for quark star configurations with possible diquark condensation. Due to the conditions of charge neutrality and β-equilibrium the flavor asymmetry increases with the number density of trapped antineutrinos. Above a critical value of the antineutrino chemical potential of 30 MeV diquark condensation is inhibited at low densi...
متن کاملEffects of quark matter and color superconductivity in compact stars
The equation of state for quark matter is derived for a nonlocal, chiral quark model within the mean field approximation. We investigate the effects of a variation of the form factors of the interaction on the phase diagram of quark matter under the condition of β equilibrium and charge neutrality. Special emphasis is on the occurrence of a diquark condensate which signals a phase transition to...
متن کاملLong Gamma Ray Bursts from Quark Stars
— If strange quark matter (SQM) is the true ground state of hadronic matter, then conversion of neutron stars (NS) into quark stars (QS) could release some 10 erg. We describe a scenario of burning of a NS into a hot, differentially rotating QS. Emission of released non-baryonic energy through the QS surface is discussed. The rôle of magnetobuoyancy of SQM is mentioned. The outflow of γee lasti...
متن کاملNeutrino and Electron-positron Pair Emission from Phase-induced Collapse of Neutron Stars to Quark Stars
We study the energy released from phase-transition induced collapse of neutron stars, which results in large amplitude stellar oscillations. To model this process we use a Newtonian hydrodynamic code, with a high resolution shockcapturing scheme. The physical process considered is a sudden phase transition from normal nuclear matter to a mixed phase of quark and nuclear matter. We show that bot...
متن کاملAsymmetric combustion in neutron stars and a potential mechanism for gamma ray bursts
We study the transition of nuclear matter to strange quark matter (SQM) inside neutron stars (NSs). It is shown that the influence of the magnetic field expected to be present in NS interiors has a dramatic effect on the propagation of a laminar deflagration (widely studied so far), generating a strong acceleration of the flame in the polar direction. This results in a strong asymmetry in the g...
