Quark-Hadron Hybrid Stars as Remnants of Supernovae Explosions
Published online by Cambridge University Press: 25 May 2016
Extract
It is expected that at explosion of Supernovae the mechanism of producing a shock wave is based on subatomic interactions, and the remnant of the supernovae explosion can be a hybrid quark-hadron star. Since the temperature in the centre of collapsing stars reaches of order T = 6 − 8 · 1010K and density electrons from the top of the Fermi sea can be captured and convert protons into neutrons via e− + p → n + ve. The capture of electrons results in a neutronization burst (V.S. Imshennik 1988). Core collapse of the progenitor star becomes essentially a free fall with a time scale
. When the central density of the core reaches supernuclear densities the repulsive QCD forces becomes essential. This can bring about manifestations of quark-hadron phase transitions (A. Dar 1997). After the explosion, from the remaining matter is probably formed a hybrid star.
