The Crustal Rigidity of a Neutron Star and Implications for PSR B1828−11 and Other Precession Candidates
The Crustal Rigidity of a Neutron Star and Implications for PSR B1828−11 and Other Precession Candidates
Like the Earth, a neutron star (NS) can undergo torque-free precession because some piece ΔId of its inertia tensor remains tied to the crust's principal axes, as opposed to following the crust's angular velocity vector. The (body frame) precession frequency νp is νsΔId/IC, where νs is the NS's spin frequency …
