Influence of $\\delta$-meson on both static and rotating neutron star is discussed. Inclusion of $\\delta$-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 $\\delta$-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 $\\delta-$meson.","authors_text":"Bharat Kumar, S. K. Biswal, S. K.
