Strange matter in rotating compact stars
We have constructed equations of state involving various exotic forms of matter with large strangeness fraction such as hyperon matter, Bose-Einstein condensates of antikaons and strange quark matter. First order phase transitions from hadronic to antikaon condensed and quark matter are considered here. The hadronic phase is described by the relativistic field theoretical model. Later those equ...
متن کاملGluons at finite temperature in Landau gauge Yang–Mills theory
The infrared behavior of Yang-Mills theory at finite temperature provides access to the role of confinement. In this review recent results on this topic from lattice calculations and especially Dyson–Schwinger studies are discussed. These indicate persistence of a residual confinement even in the high–temperature phase. The confinement mechanism is very similar to the one in the vacuum for the ...
متن کاملStrange Quark Matter and Compact Stars
Astrophysicists distinguish between three different kinds of compact stars. These are white dwarfs, neutron stars, and black holes. The former contain matter in one of the densest forms found in the Universe which, together with the unprecedented progress in observational astronomy, makes such stars superb astrophysical laboratories for a broad range of most striking physical phenomena. These r...
متن کاملMetastable strange matter and compact quark stars
Strange quark matter in beta equilibrium at high densities is studied in a quark confinement model. Two equations of state are dynamically generated for the same set of model parameters used to describe the nucleon: one corresponds to a chiral restored phase with almost massless quarks and the other to a chiral broken phase. The chiral symmetric phase saturates at around five times the nuclear ...
متن کاملStrange mesons in nuclear matter at finite temperature
We study the properties of K and K̄ mesons in nuclear matter at finite temperature from a chiral unitary approach in coupled channels which incorporates the sand p-waves of the kaon-nucleon interaction. The in-medium solution accounts for Pauli blocking effects, mean-field binding on all the baryons involved, and π and kaon self-energies. We calculate K and K̄ (off-shell) spectral functions and s...
