Effects of isovector scalar meson on hyperon star

Nuclear Theory 2016-03-01 v1

Abstract

We study the effects of isovector-scalar (δ\delta)-meson on neutron star. Influence of δ\delta-meson on both static and rotating neutron star is discussed. Inclusion of δ\delta-meson in a neutron star system consisting of proton, neutron and electron, make the equation of state stiffer in higher density and consequently increases the maximum mass of the star. But induction of δ\delta-meson in the hyperon star decreases the maximum mass of the hyperon star. This is due to the early evolution of hyperons in presence of δ\delta-meson.
