Mixing and Magnetic Fields in Asymptotic Giant Branch Stars in the Framework of FRUITY Models
Universe, 2021 In the last few years, the modeling of asymptotic giant branch (AGB) stars has been much investigated, both focusing on nucleosynthesis and stellar evolution aspects. Recent advances in the input physics required for stellar computations made it possible

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers
Annalen der Physik, Volume 536, Issue 2, February 2024.Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Supernova neutrinos and nucleosynthesis [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2014 Observations of metal-poor stars indicate that at least two different nucleosynthesis sites contribute to the production of r-process elements.

Big Bang Nucleosynthesis Constraints on f (T, TG) Gravity
Universe, 2022 We confront f(T,TG) gravity, with big bang nucleosynthesis (BBN) requirements. The former is obtained using both the torsion scalar, as well as the teleparallel equivalent of the Gauss–Bonnet term, in the Lagrangian, resulting to modified Friedmann ...

Journal of Geophysical Research: Planets, Volume 129, Issue 2, February 2024.Abstract The nucleosynthetic Cr isotope anomalies provides useful information to trace the source and origin of extraterrestrial samples, but it is usually influenced by high‐energy cosmic rays, and evaluating such effect of cosmic rays in lunar samples is especially important.

The Nucleosynthesis and Reaction Rates of Fluorine 19 ($^{19}F$) in the Sun
, 2019 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

Nuclear astrophysicists at war
Natural Sciences, Volume 4, Issue 1, January 2024.The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...

Nucleosynthesis Without Computer [PDF]
International Journal of Theoretical Physics, 2004 I derive completely analytically the time evolution and final abundances of the light elements (up to Be-7) formed in the big-bang nucleosynthesis.This highlights an interesting physics taking place during the formation of light elements in the early universe.

Neutrino Nucleosynthesis of radioactive nuclei in supernovae [PDF]
, 2015 We study the neutrino-induced production of nuclides in explosive supernova nucleosynthesis for progenitor stars with solar metallicity and initial main sequence masses between 15 M$_\odot$ and 40 M$_\odot$. We improve previous investigations i) by using
