Heavy Element Nucleosynthesis

EPJ Web of Conferences, 2018
This contribution deals with the important subject of the nucleosynthesis of heavy elements in the Galaxy. After an overview of several observational features, the physical processes responsible mainly for the formation of heavy elements will be ...

Direct study of the 21Ne(p,γ)22Na reaction deep underground at LUNA [PDF]

EPJ Web of Conferences
The 21Ne(p,γ)22Na reaction is part of the NeNa cycle, which contributes to hydrogen burning and nucleosynthesis in various stellar environments. The major astrophysical impact of this reaction is the production of the unstable nucleus of 22Na, recognized

Evolution and nucleosynthesis of helium-rich asymptotic giant branch models

, 2015
There is now strong evidence that some stars have been born with He mass fractions as high as $Y \approx 0.40$ (e.g., in $\omega$ Centauri). However, the advanced evolution, chemical yields, and final fates of He-rich stars are largely unexplored.

Studying stars by going underground: the LUNA experiment at Gran Sasso Laboratory

EPJ Web of Conferences, 2014
Cross sections of astrophysically relevant reactions are essential ingredients for element nucleosynthesis, energy generation and neutrino fluxes in stellar environments.

Gamma-ray line emission from OB associations and young open clusters

, 1999
OB associations and young open clusters constitute the most prolific nucleosynthesis sites in our Galaxy. The combined activity of stellar winds and core-collapse supernovae ejects significant amounts of freshly synthesised nuclei into the interstellar ...

On the origin of fluorine in the Milky Way

, 2004
The main astrophysical factories of fluorine (19F) are thought to be Type II supernovae, Wolf-Rayet stars, and the asymptotic giant branch (AGB) of intermediate mass stars.

Metal-enriched Pair-instability Supernovae: Effects of Rotation

The Astrophysical Journal
In this paper, we revisit metal-enriched rotating pair-instability supernovae (PISNe) models for metallicities consistent with the Small Magellanic Cloud, the Large Magellanic Cloud (LMC), and 0.1 Z _⊙ .
