Abstract

fetched live from OpenAlex

We report on the initial analysis of a Herschel-PACS full range spectrum of Neptune, covering the 51-220 m range with a mean resolving power of 3000, and complemented by a dedicated observation of CH 4 at 120 m. Numerous spectral features due to HD (R(0) and R(1)), H 2 O, CH 4 , and CO are present, but so far no new species have been found. Our results indicate that (i) Neptune's mean thermal profile is warmer by 3 K than inferred from the Voyager radio-occultation; (ii) the D/H mixing ratio is (4.5 1) 10 -5 , confirming the enrichment of Neptune in deuterium over the protosolar value (2.1 10 -5 ); (iii) the CH 4 mixing ratio in the mid stratosphere is (1.5 0.2) 10 -3 , and CH 4 appears to decrease in the lower stratosphere at a rate consistent with local saturation, in agreement with the scenario of CH 4 stratospheric injection from Neptune's warm south polar region; (iv) the H 2 O stratospheric column is (2.1 0.5) 10 14 cm -2 but its vertical distribution is still to be determined, so the H 2 O external flux remains uncertain by over an order of magnitude; and (v) the CO stratospheric abundance is about twice the tropospheric value, confirming the dual origin of CO suspected from ground-based millimeter/submillimeter observations.

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.
