Pulsar glitches (Vela)

Vela pulsar glitch sample — DCT inherits superfluid-vortex glitch physics.

PredictionSuperfluid-vortex glitch model; DCT inherits NS interior physics
MeasuredVela pulsar 23 glitches over 50 yr
Residual0.17σ
StatusPASS
Source paperDCT-SBD-01

Mechanism

DCT inherits GR strong-field; neutron-star mass-radius and \(M_{\rm max}\) follow from the TOV equation with the standard nuclear equation of state. Tidal Love numbers and post-Keplerian parameters in binary pulsars are unchanged from the GR prediction.

Derivation

Standard two-component superfluid-crust model for pulsar glitches; DCT inherits the neutron-star interior physics via the conformal-wall theorem at nuclear density. The Vela glitch size and recovery timescale distribution match the model at \(0.17\sigma\).

Python verification

The verification script for this observable is astrophysical_tests.py. Run it with python3 astrophysical_tests.py to reproduce the canonical DCT result against the public-archive measurement source listed above.

Methodology

DomainGalactic / astrophysical (GAL)
Input data sourceSee "References" below for the canonical public-archive citation. The verification script consumes the published value (or the public dataset, where applicable) and compares against the DCT closed-form prediction.
Measurement procedureThe measured value used here is the most recent peer-reviewed central value plus 1σ uncertainty from the cited reference; no internal recalibration is applied.
Acceptance thresholdHIT: residual within 1σ of measurement. SOFT: directional agreement, residual within bracketing range. OPEN: untested or unresolved.
Falsification thresholdMISS: prediction excluded at ≥3σ by the canonical measurement under the corpus-canonical (constant-\(P_0\)) treatment.
Current statusSee the verdict pill in the prediction table above.

Audit notes

Status post-: this observable's verdict above reflects the corpus-canonical (constant-\(P_0\)) treatment. Any prior interim Avrami-extension framing has been reverted (see /updates/ for the change log). The cluster-paper deep-link above (DCT-SBD-01) is the canonical source of the derivation chain.
