Abstract

fetched live from OpenAlex

Recent observations of the star-to-star abundance variations well below the bump luminosity in globular clusters have raised the weight of the primordial scenario. So far, intermediate-mass AGB stars have been considered as the most likely primordial sources of these abundance variations. I present some arguments against this idea and propose alternative sources. These are RGB and/or AGB stars a little bit more massive than the present-day MSTO stars that had experienced enhanced extra mixing in the past. In this case the more preferable way of polluting the lower mass MS stars by nuclearly processed material would be mass transfer in binaries rather than stellar winds from single stars.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
