The Possibly Remnant Massive Outflow in G5.89‐0.39. I. Observations and Initial Magnetohydrodynamic Simulations
Bibliographic record
Abstract
We have obtained maps of the large-scale outflow associated with the UC H II region G5.89-0.39 in CO and 13 CO ( J = 3-2), SiO ( J = 8-7, J = 5-4), SO 2 ( J = 13 2,12 -13 1,13 ), 13 and H 13 CO + ( J = 4-3). From these maps we have been able to determine the mass (3.3 M ☉ ), momentum (96 M ☉ km s -1 ), energy (3.5 × 10 46 ergs), mechanical luminosity (141 L ☉ ), and mass-loss rate (~ 1 × 10 -3 M ☉ yr -1 ) in the large-scale outflow. The observationally derived parameters were used to guide three-dimensional magnetohydrodynamic models of the jet-entrained outflow. Through the combination of observations and simulations, we suggest that the large-scale outflow may be inclined by approximately 45° to the line of sight, and that the jet entraining the observed molecular outflow may have been active for as little as 1000 years, half the kinematic age of the outflow.

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.
