Thermonuclear reaction rate of 18O(p,γ)19F Open
For stars with 0.8 M⊙ ≤ M ≤ 8.0 M⊙, nucleosynthesis enters its final phase during the asymptotic giant branch (AGB) stage. During this evolutionary period, grain condensation occurs in the stellar atmosphere, and the star experiences s…

The N14(p,γ)O15 reaction regulates the power generated by the CN cycle and thus impacts the structure and evolution of every star at some point in its life. The lowest positive-energy resonance in this reaction is located at Erc.m.=259 keV…

Measurement of the e r c.m. = 138 keV resonance in the 23 Na(p, γ) 24 Mg reaction and the abundance of sodium in AGB stars Open
Globular clusters represent some of the oldest stellar aggregations in the universe. As such, they are used as testing grounds for theories of stellar evolution and nucleosynthesis. Astronomical observations have shown star-to-star abundan…

For 0.8 Mȯ ≤ M ≤ 8.0 Mȯ stars, the final phase of nucleosynthesis occurs during the asymptotic giant branch (AGB) stage. Grain condensation and significant mass loss transpires during this stellar evolutionary period, and presolar grains r…

The 14N(p, γ)15O reaction regulates the rate of energy production for stars slightly more massive than the sun throughout stable hydrogen burning on the main sequence. The 14N(p, γ)15O reaction rate also determines the luminosity for all s…
