A complex structure of escaping helium spanning more than half the orbit of the ultra-hot Jupiter WASP-121b
Bibliographic record
Abstract
This dataset contains the full-orbit helium phase-curve observations of the ultra-hot Jupiter WASP-121 b obtained with the James Webb Space Telescope (JWST) Near Infrared Imager and Slitless Spectrograph (NIRISS). The Python scripts used to produce the figures shown in the paper are provided with a README file, the extracted data from NAMELESS and exoTEDRF, the best-fit EVE toy-model. The data include flux measurements, wavelength calibrations, and associated uncertainties, capturing helium absorption over nearly 60% of the planetary orbit. These observations reveal a strong atmospheric outflow forming two distinct tails with different kinematics and provide critical constraints on hydrodynamic escape in highly irradiated exoplanets. The dataset supports analyses of mass-loss rates, atmospheric dynamics, and comparisons with theoretical models. It is intended for use in exoplanet atmosphere studies, model validation, and educational purposes.
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 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.
