# The Nucleosynthesis and Reaction Rates of Fluorine 19 ($^{19}F$) in the Sun

## TL;DR

This paper explores the nucleosynthesis process of fluorine-19 in the Sun, calculating reaction rates and stability conditions, and identifying key resonances that influence its abundance.

## Contribution

It provides a detailed analysis of the nuclear reactions and conditions leading to fluorine-19 production in the Sun, including reaction rates and resonance contributions.

## Key findings

- $^{19}F$ is stable with A=19 and mass excess -1.4874 MeV.
- Reaction rate of $^{15}N$($\alpha$, $\gamma$)$^{19}F$ is dominated by low-energy resonances.
- Enhanced $^{19}F$ abundance due to resonance contributions in the solar envelope.

## Abstract

We investigate the abundance of $^{19}F$ in the Sun through the nucleosynthesis scenario. In addition, we calculate the rate equations and reaction rates of the nucleosynthesis of $^{19}F$ at different temperature scale. Other important functions of this nucleosynthesis (nuclear partition function and statistical equilibrium conditions) are also obtained. The resulting stability of $^{19}F$ occurs at nucleus with A = 19 and Mass Excess= -1.4874 MeV. As a result, this will tend to a series of neutron captures and beta-decay until $^{19}F$ is produced. The reaction rate of $^{15}N$ ($\alpha$, $\gamma$) $^{19}F$ was dominated by the contribution of three low-energy resonances, which enhanced the final $^{19}F$ abundance in the envelope.
