From 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 کاملInternal Constitution of Neutron and Strange Stars
In the first of these two lectures I will discuss the rich constitution of neutron stars as a consequence of the Pauli principle which is engaged by the dominance of gravity over the nuclear force. Three especially interesting phenomena are discussed in this contect—(1) a mechanism for the formation of low-mass black holes distinct in their mass-range from the black holes formed in the prompt c...
متن کاملSurface gravity of neutron stars and strange stars
The upper bound on the value of the surface gravity, gs, for neutron stars with equations of state respecting vsound ≤ c, is derived. This bound is inversely proportional to the maximum allowable mass Mmax, and it reads gs ≤ 1.411× 10 15 (Mmax/M⊙) −1 cm s. It implies an absolute upper bound 7.4× 10 cm s if one uses the 2σ lower bound on the neutron mass measured recently in 4U1700-37, 1.9M⊙. A ...
متن کاملStrange Dibaryons in Neutron Stars and in Heavy-Ion Collisions
The formation of dibaryons with strangeness are discussed for the interior of neutron stars and for central relativistic heavy-ion collisions. We derive limits for the properties of H-dibaryons from pulsar data. Signals for the formation of possible bound states with hyperons at BNL’s Relativistic Heavy-Ion Collider (RHIC) are investigated by studying their weak decay patterns and production ra...
متن کاملAvoided crossings in radial pulsations of neutron and strange stars
Radial pulsations of neutron stars and strange quark stars with nuclear crust are studied. The avoided crossing phenomenon occurring for the radial modes is found and discussed. Neutron star models are constructed using a realistic equation of state of dense matter and strange star models using a phenomenological bag model of quark matter. The eigenfrequencies of the three lowest modes of linea...
