Optical and X-ray variations during five outbursts of Aql X-1 in 3.6 yr from 2016
Bibliographic record
Abstract
ABSTRACT We analysed optical/X-ray quasi-simultaneous light curves of Aql X-1, obtained by Monitor of All-sky X-ray Image, Zwicky Transient Facility, and Las Cumbres Observatory Global Telescope network in about 3.6 yr from 2016, for understanding electromagnetic radiation mechanisms during its outbursts. As a result, we confirmed that five outbursts had detected in the epoch, and that three outbursts underwent the X-ray state transition across Low-Hard, In-Transition, and High-Soft state while remaining two outbursts stayed in the Low-Hard state. We found that the optical spectral energy distribution in the High-Soft state is consistent with a simplified irradiated disc model, and that the optical colour/magnitude variation can be explained by variations in the X-ray luminosity and the disc geometrical thickness.

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.
