Abstract
- We investigate neutron star moments of inertia from Bayesian posterior probability distributions of the nuclear equation of state that incorporate information from microscopic many-body theory and empirical data of finite nuclei. We focus on PSR J0737-3039A and predict that for this 1.338M⊙ neutron star the moment of inertia lies in the range 1.04×1045gcm²<I<1.51×1045gcm² at the 95% credibility level, while the most probable value for the moment of inertia is ˜I=1.36×1045gcm². Assuming a measurement of the PSR J0737-3039A moment of inertia to 10% precision, we study the implications for neutron star radii and tidal deformabilities. We also determine the crustal component of the moment of inertia and find that for typical neutron star masses 1.3M⊙<M<1.5M⊙ the crust contributes 1-6% of the total moment of inertia, below what is needed to explain large pulsar glitches in the scenario of strong neutron entrainment.
