Abstract
We study the effects of isovector-scalar ()-meson on neutron star. Influence of -meson on both static and rotating neutron star is discussed. Inclusion of -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 -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 meson.
