MORPHOKINEMATIC PROPERTIES OF THE 21 μm SOURCE IRAS 07134+1005
Bibliographic record
Abstract
We report the results of a Submillimeter Array (SMA) interferometric observation of 21 μm source IRAS 07134+1005 in the CO J = 3–2 line. In order to determine the morphokinematic properties of the molecular envelope of the object, we construct a model using the Shape software to model the observed CO map. We find that the molecular gas component of the envelopes can be interpreted as a geometrically thick expanding torus with an expanding velocity of 8 km s −1 . The inner and outer radii of the torus determined by fitting Shape models are 1 2 and 3 0, respectively. The inner radius is consistent with the previous values determined by radiative transfer modeling of the spectral energy distribution and mid-infrared imaging of the dust component. The radii and expansion velocity of the torus suggest that the central star left the asymptotic giant branch about 1140–1710 years ago, and that the duration of the equatorial enhanced mass loss is about 2560–3130 years. From the absence of an observed jet, we suggest that the formation of a bipolar outflow may lag behind in time from the creation of the equatorial torus.

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.
