Pulsar Spin-Down Against the Torsion Bound

This paper recomputes dipole magnetic fields and spin-down powers for four pulsars spanning the population from the Crab to a recycled millisecond pulsar, and evaluates the fractional correction that spin-sourced torsion in a bounced cosmology would impose on spin-down at neutron-star central densities. The headline results are as follows. Dipole field of the Crab pulsar: 3.79e+12 G; Spin-down power of the Crab pulsar: 4.46e+38 erg s-1; Dipole field of the Vela pulsar: 3.38e+12 G; Spin-down power of a recycled millisecond pulsar in the sample: 5.21e+33 erg s-1; Ratio of spin-down powers between the Crab and the millisecond pulsar: 8.56e+04; Fractional torsion correction to spin-down at a central density of ten to the eighteenth kilograms per cubic metre: 1.03e-40. All values are computed from the stated assumptions and published inputs; the study is simulated and computed, not measured.
