Braking index of PSR J1846−0258: a model of magnetic inclination evolution and its gravitational-wave implication

We explain the braking index n=2.19±0.03 of PSR J1846−0258 by incorporating the time evolution of its magnetic inclination angle and dipolar magnetic field. Based on observational timing data and the age of the associated supernova remnant (tSNR≈1.77kyr), we estimate a magnetic inclination change ra...
