摘要: We consider a universal relation between moment of inertia and quadrupole arbitrarily fast rotating neutron stars. Recent studies suggest that this breaks down for rotation. find it is still among various suggested equations state constant values certain dimensionless parameters characterizing the magnitude One these includes star radius, leading to new expressing radius through mass, frequency, spin parameter. This can become powerful tool measurements.
