Timing and Precession of the Young, Relativistic Binary Pulsar PSR J1906+0746
Bibliographic record
Abstract
We present an updated timing solution and an analysis of the profile evolution—including precession and beam shape—of the young, relativistic binary pulsar J1906+0746. The 144‐ms pulsar, in a 3.98‐hour orbit with eccentricity 0.085 [1], was initially discovered during the early stages of the ALFA (Arecibo L‐band Feed Array) pulsar survey [2] using the 305‐metre Arecibo telescope and was subsequently found in archival Parkes Multibeam Survey data. We have since been regularly monitoring the system using the Arecibo and Green Bank telescopes, and include data from the Jodrell Bank, Parkes, Nancay and Westerbork telescopes. The nature of the binary companion will also be discussed based on improved estimates of the total and companion masses obtained from the updated timing solution.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
