Abstract

fetched live from OpenAlex

High spatial resolution images have been taken on the Gemini North telescope of the classical T Tauri star RY Tauri. The Hα image, with the continuum properly subtracted, shows a jet extending out to at least 31'' at a position angle of about 295° from the star. A counterjet extending to at least 3.5' in the opposite direction is also visible. The knots in the inner part of the jet are probably less than 10 years old. This new Herbig-Haro bipolar jet has been labeled HH 938. Comparison with previous Hubble Space Telescope (HST) images revealed a probable tangential motion of the brightest knot by about 165 km s−1. The orientation of the disk, as given by the average position angle of published polarization measurements, is ≈20°, or almost perpendicular to the direction of the jet. Because of the proximity of its inner knots to the star and their very young dynamical age, this jet is a very good candidate to study jet emission mechanisms.

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.
