Performing Bayesian Analyses With AZURE2 Using BRICK: An Application to the 7Be System

Daniel Odell et al.

Summary: A Markov Chain Monte Carlo sampler emcee has been implemented, creating the Bayesian R-matrix Inference Code Kit (BRICK). Bayesian uncertainty estimation has been carried out for simultaneous R-matrix fit of the He-3 (alpha,gamma)Be-7 and He-3 (alpha,alpha)He-3 reactions to gain further insight.

Direct Measurement of the Astrophysical 19F(p,αγ)16O Reaction in the Deepest Operational Underground Laboratory

L. Y. Zhang et al.

Summary: Fluorine is considered one of the most interesting elements in nuclear astrophysics, and the direct measurements of the F-19(p, alpha gamma)O-16 reaction channel have provided new insights into the reaction rate at relevant astrophysical energies. The experiment conducted at the Jinping Underground Nuclear Astrophysics facility revealed deviations from previous theoretical predictions in low-energy S factors and significantly reduced uncertainties in the data. This study highlights the importance of experimental data in refining our understanding of nuclear astrophysical processes.

Uncertainties in the 18F(p, α)15O reaction rate in classical novae

D. Kahl et al.

Summary: The study examined uncertainties in the calculation of the F-18(p, alpha) reaction rate, aiming to identify the factors that most affect the predicted abundance of F-18 ejected from novae. The research highlighted the highly uncertain nature of the F-18(p, alpha) rate at nova temperatures, emphasizing the need for future experimental work to focus on determining quantum properties of subthreshold states more precisely.

Strong and durable fluorine-implanted targets developed for deep underground nuclear astrophysical experiments

Liyong Zhang et al.

Summary: The study found that traditional fluorine targets are prone to material loss in high-current experiments, while targets prepared by implantation method are more stable. The optimal target scheme is to first implant F ions into pure Fe backing, then sputter a Cr layer to further prevent material loss.

19F(p, γ)20Ne and 19F(p, αγ)16O reaction rates and their effect on calcium production in Population III stars from hot CNO breakout

R. J. DeBoer et al.

Summary: First generation stars evolve differently due to their initial primordial abundance composition, lacking carbon, oxygen, and nitrogen. The enhanced abundance of calcium in the most metal-poor stars could potentially be a result of high temperature H-burning in the first massive stars, but the rate uncertainty for this enrichment is considerable. Additional experimental measurements are necessary to determine the cause of calcium enrichment in metal-poor stars.

Thermonuclear 19F(p, α)16O Reaction Rate Revised and Astrophysical Implications

L. Y. Zhang et al.

Summary: The study re-evaluated experimental data to calculate the F-19(p, alpha)O-16 reaction rate across a wide temperature range. The new rate shows significant differences at different temperatures and has a strong impact on the destruction of F-19 in the CNO cycle at low temperatures. Further research is needed to verify the results and understand the implications of the findings.
