Strengthening the link between fullerenes and a subset of diffuse interstellar bands
Bibliographic record
Abstract
ABSTRACT A debate persists regarding the correlation between the diffuse interstellar bands (DIBs) 9577 and 9632 Å, and whether they share a common molecular carrier (i.e. C$_{60}^{+}$). A robust high correlation determination emerges after bridging the baseline across an order of magnitude ($\simeq 50 - 700$ mÅ, $r=0.93\pm 0.02$), and nearly doubling the important higher equivalent width domain by adding new Mg ii-corrected sightlines. Moreover, additional evidence is presented of possible DIB linkages to fullerenes, whereby attention is drawn to DIBs at 7470.38, 7558.44, and 7581.47 Å, which match the Campbell experimental results for C$_{70}^{+}$ within 1 Å, and the same is true of 6926.48 and 7030.26 Å for C$_{70}^{2+}$. Yet their current correlation uncertainties are unsatisfactory and exacerbated by expectedly low equivalent widths (e.g. $\overline{EW}=4$ mÅ for 6926.48 Å), and thus further observations are required to assess whether they represent a bona fide connection or numerical coincidence.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
