Abstract

fetched live from OpenAlex

The presence of broad absorption features of telluric ozone close to the Be ii doublet seems to have been ignored in the literature. Actually, for objects with small or negative velocities the Be ii lines are not affected by ozone absorption; however, for objects with high positive velocities (as are found in some globular cluster members and Population II objects) the stellar Be ii lines will be red-shifted onto the flanks of a nearby ozone feature to an extent that could have a significant impact on accurate calculations of stellar Be abundances.

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.
