Abstract
Giant planets like Jupiter, which undergo strong convection in their gaseous envelopes, can develop a composition gradient (CG) during their formation. During their early evolution, a convection zone (CZ) propagates inwards as the planet cools. How quickly does the CZ move inward? What is the mixing mechanism? Using numerical simulations, we find that the CZ evolution rate depends on the cooling speed and initial CG size (a large CG slows the evolution). Further, we find that turbulent motions near the CZ boundary carry enough energy to lift and mix heavier fluid from below. This ``entrainment'' is important in CZ growth. We present a simple model that reproduces the numerical results.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
