Abstract
The thermal dust continuum emission at 848 μm from the globule CB 068, a Class 0 young stellar object (YSO), reveals strong linear polarization percentage values (up to 11%) in two polarized-intensity regions located on either side of the center, away from the twin CO outflows. At the 5% polarized intensity level, the two highly polarized regions have a radial separation of 0.01 pc from the center of the Bok globule. The two polarized regions are located on either side of the axis of the twin CO outflows, with polarization contours paralleling the outflows. The linear polarization orientation leads us to deduce that, in the inner part of the polarized-intensity regions, the electric field vector roughly follows the boundary of a pseudodisk or bar (the pseudodisk or bar was previously detected both in dust and in ammonia emission). The linear polarization orientation, within a radius of 0.03 pc, can be matched roughly to an infalling halo-to-disk magnetic field morphology, excluding the regions of the external envelope and near the CO outflows. On a 0.04 pc scale, our model predictions for CB 068 give a pseudodisk diameter of about 8800 AU. We predict a magnetic field strength (over 0.03 pc) of about 150 μG, which comes about from the Chandrasekhar-Fermi method (via the ratio of the line of sight velocity dispersion to the polarization angle dispersion).

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.
