Abstract

We describe possible scenarios of quark deconfinement in compact stars and we analyze their astrophysical implications. The quark deconfinement process can proceed rapidly, as a strong deflagration, releasing a huge amount of energy in a short time and generating an extra neutrino burst. If energy is tranferred efficiently to the surface, like e.g. in the presence of convective instabilities, this burst could contribute to revitalize a partially failed SN explosion. We discuss how the neutrino observations from SN1987A would fit in this scenario. Finally, we focus on the fate of massive and rapidly rotating progenitors, discussing possible time separations between the moment of the core collapse and the moment of quark deconfinement. This mechanism can be at the basis of the interpretation of gamma ray bursts in which lines associated with heavy elements are present in the spectrum.

Quark matter in astrophysics and cosmology

Conference Olinto, A

We dicuss the role of quark matter in astrophysics and cosmology. The implications of the dynamics of the quark-hadron phase transition in the early universe for the element abundances from big bang nucleosynthesis and the composition of the dark matter in the universe are addressed. We discuss the possibility of deciding on an equation of state for high density matter by observing the cooling of a neutron star remnant of SN1987A. Quark matter models for the Centauros events, Cygnus X-3 cosmic ray events, high energy gamma-ray bursts and the solar neutrino problem are described. 25 refs., 3 figs.

Astrophysical implications of equation of state for hadron-quark mixed phase: Compact stars and stellar collapses

Journal Article Nakazato, Ken'ichiro; Yamada, Shoichi; Sumiyoshi, Kohsuke - Physical Review. D, Particles Fields

We construct an equation of state including the hadron-quark phase transition. The mixed phase is obtained by the Gibbs conditions for finite temperature. We adopt the equation of state based on the relativistic mean field theory for the hadronic phase, taking into account pions. As for the quark phase, the MIT bag model of the deconfined 3-flavor strange quark matter is used. As a result, our equation of state is thermodynamically stable and qualitatively exhibits the desired properties of hadron-quark mixed matter, such as the temperature dependence of the transition density. The pions raise the transition density because they makemore »« less

DISCOVERY OF A GIANT, HIGHLY COLLIMATED JET FROM SANDULEAK'S STAR IN THE LARGE MAGELLANIC CLOUD

Journal Article Angeloni, R; Di Mille, F; Bland-Hawthorn, J - Astrophysical Journal Letters

Highly collimated gas ejections are among the most dramatic structures in the universe, observed to emerge from very different astrophysical systems-from active galactic nuclei down to young brown dwarf stars. Even with the huge span in spatial scales, there is convincing evidence that the physics at the origin of the phenomenon, namely, the acceleration and collimation mechanisms, is the same in all classes of jets. Here we report on the discovery of a giant, highly collimated jet from Sanduleak's star in the Large Magellanic Cloud (LMC). With a physical extent of 14 pc at the distance of the LMC, itmore »« less

Neutron stars, fast pulsars, supernovae and the equation of state of dense matter

Conference Glendening, N

We discuss the prospects for obtaining constraints on the equation of state from astrophysical sources. Neutron star masses although few are known at present, provide a very direct constraint in as much as the connection to the equation of state involves only the assumption that Einstein's general theory of relativity is correct at the macroscopic scale. If the millisecond pulses briefly observed in the remnant of SN1987A can be attributed to uniform rotation of a pulsar, then a very severe constraint is placed on the equation of state. The theory again is very secure. The precise nature of the constraintmore »« less

Supernova explosion and black hole formation with hadron-quark phase transition

Journal Article Nakazato, Ken'ichiro - AIP Conference Proceedings

Hadronic matter undergoes a deconfinement transition to quark matter at high temperature and/or high density. It would be realized in collapsing cores of massive stars. The fates of core collapses are investigated for various cases. Equations of state including the hadron-quark phase transition with different values of bag constant are used. As a result, for the case with a small bag constant (i.e. the transition occurs at low density), the second bounce revives the shock wave leading to explosion for the model with 15 solar mass. The systematics on the bag constant is also studied for the black hole formationmore » of a 40 solar mass progenitor.« less
