Abstract

fetched live from OpenAlex

EE Cam is a previously little-studied δ Scuti pulsator with amplitudes between those of the HADS (high-amplitude δ Scuti star) group and average low-amplitude pulsators. Since the size of stellar rotation determines both which pulsation modes are selected by the star as well as their amplitudes, this star offers a great opportunity to examine the astrophysical connections. Extensive photometric measurements covering several months were carried out. Fifteen significant pulsation frequencies were extracted. The dominant mode at 4.934 cycles day -1 was identified as a radial mode by examining the phase shifts at different wavelengths. Medium-dispersion spectra yielded a v sin i value of 40 ± 3 km s -1 . This shows that EE Cam belongs to the important transition region between HADSs and normal δ Scuti 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.

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.
