Abstract
GX301-2 is an accreting neutron star in an eccentric orbit () with a massive early-type stellar companion. GX301-2 accretes from the stellar wind and exhibits regular X-ray flares approximately 1.4 days prior to periastron passage. Long-term continuous X-ray monitoring of GX301-2 by the RXTE/All-Sky-Monitor has now been carried out for a period of 5 years. These data now comprise the best observations of the orbital X-ray light curve. The main flux peak just prior to periastron is clearly seen, as well as a secondary broad peak near apastron. CGRO/BATSE observations have provided new improved orbital parameters. The constraint on the orbital inclination is examined. Then the GX301-2 orbital light curve is modeled using wind, disk and stream models. The conclusion is that only a stellar wind plus mass stream is consistent with the data. The wind model is further supported by calculations of the stream flow from the primary and the expected orbital phases that the neutron star crosses the stream.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
