Abstract
We examine the impact of the strength of the ${E}_{R}=127$ keV, $^{26}\mathrm{Al}(p,\ensuremath{\gamma})^{27}\mathrm{Si}$ resonance on $^{26}\mathrm{Al}$ production in classical nova explosions and asymptotic giant branch (AGB) stars. Thermonuclear $^{26}\mathrm{Al}(p,\ensuremath{\gamma})^{27}\mathrm{Si}$ reaction rates are determined using different assumed strengths for this resonance and representative stellar model calculations of these astrophysical environments are performed using these different rates. Predicted $^{26}\mathrm{Al}$ yields in our models are not sensitive to differences in rates determined using zero and a commonly stated upper limit corresponding to $\ensuremath{\omega}{\ensuremath{\gamma}}_{\mathrm{UL}}=0.0042$ $\ensuremath{\mu}\mathrm{eV}$ for this resonance strength. Yields of $^{26}\mathrm{Al}$ decrease by 6% and, more significantly, up to 30%, when a strength of $24\ifmmode\times\else\texttimes\fi{}\ensuremath{\omega}{\ensuremath{\gamma}}_{\mathrm{UL}}=0.1$ $\ensuremath{\mu}\mathrm{eV}$ is assumed in the adopted nova and AGB star models, respectively. Given that the value of $\ensuremath{\omega}{\ensuremath{\gamma}}_{\mathrm{UL}}$ was deduced from a single, background-dominated $^{26}\mathrm{Al}(^{3}\mathrm{He},d)^{27}\mathrm{Si}$ experiment where only upper limits on differential cross sections were determined, we encourage new experiments to confirm the strength of the 127-keV resonance.

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; both teacher heads agree on what is shown here.
