Photometry of balloon 090100001 with the Himalayan Chandra Telescope
Bibliographic record
Abstract
About one tenth of all hot subluminous B stars pulsate non-radially with periods of 80 -- 600s; the oscillations are identified with pressure modes. At lower effective temperatures, another group pulsates non-radially with periods > 3,000,s; these oscillations have been identified with gravity modes. If sufficient modes can be identified, such oscillations can provide information about the interior of a star. One pulsating sdB star -- balloon 090100001 -- lies at the boundary of the hot and cool groups, and shows both short and long-period oscillations. To study its interior structure in detail, we carried out a multi-site observing campaign in 2005 August in order to obtain a very precise light curve and hence to identify the modes of oscillation. This campaign involved four telescopes including the Himalayan Chandra Telescope (HCT), the William Herschel Telescope (in La Palma), the Canada France Hawaii Telescope and the Faulkes Telescope North (both in Hawaii). Here we report the HCT observations of balloon 090100001.

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.
