Abstract

fetched live from OpenAlex

In the binary radio pulsar system J0737−3039, the slow pulsar B shows intense orbital modulations, with these being especially bright at two short orbital phases. We propose that these modulations are due to distortion of the pulsar B magnetosphere by the pulsar A wind which produces orbital phase-dependent changes in the direction along which the radio waves are emitted. In our model, pulsar B is intrinsically bright at all times but its radiation beam misses the Earth at most orbital phases. We employ a simple model of the distorted B magnetosphere using stretching transformations of Euler potentials of dipolar fields. To fit the observations we use parameters of pulsar B derived from the modelling of A eclipses. The model reproduces two bright regions at approximately the observed orbital phases, explains variations in the pulse shape between them and the regular timing residuals within each emission window. It also makes predictions for the timing properties and secular variations of pulsar B profiles.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
