The components of the metric tensor gαβare now given by Eq. (6) below. It is then evident that in a frame comoving with the rotating star, ut =(gtt)−1/2, and the Klein
WebWe show that the neutron star minimum period of uniform rotation is determined, for causal equations of state, by the maximum value of the relativistic (compactness) parameter 2GM/Rc(2) , allowed by causality for static neutron stars, 0.7081, and by the largest measured mass of a neutron star. The relation between these three quantities, resulting … WebThe maximum change in the luminosity of a 10 M0 and 1 M0 critically rotating main-sequence star is 7% and 15%, respectively; corresponding changes in the polar radius …
