Abstract
We currently know of five distinct classes of compact pulsators, loosely defined as oscillating stars with a surface gravity above log g = 5. Three of these fall into the white dwarf regime (GW Vir, V777 Her and ZZ Ceti stars), while the other two are identified with hot B subdwarfs (EC 14026 and PG 1716 stars). In all cases, the instabilities are thought to be associated with the partial ionisation of the envelope constituents. We discuss, for each type of pulsator, our current theoretical understanding of the observed instability strips as well as the details of the driving mechanism at work. In terms of attempts at a quantitative exploitation of the observed period spectra through asteroseismology, we focus on the particularly successful case of the rapidly pulsating subdwarf B (EC 14026) stars. So far, we have been able to constrain the fundamental stellar parameters for 12 targets. This is sufficient for first comparisons with different evolutionary scenarios, and will likely play a crucial part in an eventual understanding of the formation of these objects.

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.
