Abstract

We study the effects of isovector-scalar ( $δ$ )-meson on neutron and hyperon stars. Influence of $δ$ -meson on both static and rotating stars is discussed. The $δ$ -meson in a neutron star consisting of protons, neutrons and electrons, makes the equations of states (EOS) stiffer at higher density, and consequently increases the maximum mass of the star. But induction of $δ$ -meson in the hyperon star decreases the maximum mass. This is due to the early evolution of hyperons in presence of $δ$ -meson.
