Pulsar glitches (Vela)
Vela pulsar glitch sample — DCT inherits superfluid-vortex glitch physics.
| Prediction | Superfluid-vortex glitch model; DCT inherits NS interior physics |
|---|---|
| Measured | Vela pulsar 23 glitches over 50 yr |
| Residual | 0.17σ |
| Status | PASS |
| Source paper | DCT-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
| Domain | Galactic / astrophysical (GAL) |
|---|---|
| Input data source | See "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 procedure | The 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 threshold | HIT: residual within 1σ of measurement. SOFT: directional agreement, residual within bracketing range. OPEN: untested or unresolved. |
| Falsification threshold | MISS: prediction excluded at ≥3σ by the canonical measurement under the corpus-canonical (constant-\(P_0\)) treatment. |
| Current status | See 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.
