Abstract |
Using density-dependent equations of state in the framework of relativistic mean-field, the equilibrium sequences of rotating neutron stars at the observed frequencies, 716 Hz and 1122 Hz, are constructed. The bounds of sequences, i.e. the static, Keplerian and secular axisymmetric instability, therefore, the stability region of radius-mass of star are determined. The minimum and maximum masses and their related radii for the rotating star at frequencies 716 Hz and 1122 Hz are determined by using the stability region. In each model, the cross point of Keplerian and secular sequences specifies the parameters of the most rapidly rotating star. |
