Pulsar Glitch Energetics and the Density Ceiling
Year: 2026
Type: article
Abstract: This paper computes the rotational energy released in pulsar glitches from catalogue glitch sizes and a canonical moment of inertia, compares the densities and energy densities involved with the density ceiling of a bounced cosmology, and states the resulting bound on any torsion correction to glitch dynamics. The headline results are as follows. Energy of a typical Vela glitch with fractional size one part in a million: 4.94e+42 erg; Energy of the largest catalogue glitch at three parts in a million: 1.53e+43 erg; Mean density of a canonical neutron star: 3.85e+17 kg m-3; Ratio of neutron star mean density to the density ceiling: 3.96e-41; Rotational energy released per unit volume in the largest glitch: 2.12e+23 J m-3; Fractional spin change the ceiling density would allow before torsion back-reaction at stellar density: 3.96e-41. All values are computed from the stated assumptions and published inputs; the study is simulated and computed, not measured.
