Strange 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...
متن کاملCharge and stability of strange quark matter at finite temperature
By means of the quark mass densityand temperaturedependent model, it is found that the negative charge and the higher strangeness fraction are in favor of the stability of strange quark matter at finite temperature. A critical baryon number density nBc has been found. The strange quark matter is unstable when nB < nBc. The charge and strangeness fraction dependence of stability for strange quar...
متن کاملSuperbursts from Strange Stars
Recent models of carbon ignition on accreting neutron stars predict superburst ignition depths that are an order of magnitude larger than observed. We explore a possible solution to this problem, that the compact stars in low mass X-ray binaries that have shown superbursts are in fact strange stars with a crust of normal matter. We calculate the properties of superbursts on strange stars, and t...
متن کاملFrom Neutron Stars to Strange Stars
It is generally agreed that the tremendous densities reached in the centers of neutron stars provide a high pressure environment in which numerous particles processes are likely to compete with each other. These processes range from the generation of hyperons to quark deconfinement to the formation of kaon condensates and H-matter [1]. Another striking possibility concerns the formation of abso...
متن کاملStrange stars and superbursts at near-Eddington mass accretion rates
Superbursts (SBs) were observed in systems for which accretion rate were derived to be between 0.1 to 0.25 times the Eddington limit. Recent careful assessment of four good SB candidates for GX 17+2 reveals that SB is possible even at near Eddington mass accretion rates. The scenario for SB in strange stars is that a micron-thick layer of diquarks, at the star surface, get broken due to repeate...
