Exploring the origin of the rarest stable isotopes naturally occurring on Earth with real photon beams [PDF]

open access: yesEPJ Web of Conferences
This lecture brings into focus research work that aims to advance fundamental knowledge on a forefront topic in nuclear astrophysics – the nucleosynthesis beyond Fe of the rarest stable isotopes naturally occurring on Earth (the origin of p-nuclei).

The NuGrid AGB Evolution and Nucleosynthesis Data Set

open access: yesUniverse, 2022
Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as C, N and F, and half of the elements heavier than Fe via the slow neutron

Atomic Data for Stellar Nucleosynthesis [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
AbstractStellar chemical composition analyses can only yield reliable abundances if the atomic transition parameters are accurately determined. During the last couple of decades a renewed emphasis on laboratory spectroscopy has produced large sets of useful atomic transition probabilities for species of interest to stellar spectroscopists.

A new 12C+12C reaction rate: Impact on stellar evolution [PDF]

open access: yesEPJ Web of Conferences, 2023
Among the reactions driving stellar evolution during carbon burning, 12C + 12C fusion provides the key ingredients. This system reveals many resonances, but also regions with suppressed fusion cross-sections.

Modeling The Nucleosynthesis Of Massive Stars [PDF]

open access: yes, 2003
This overview discusses issues relevant to modeling nucleosynthesis in type II supernovae and implications of detailed studies of the ejecta. After a brief presentation of the most common approaches to stellar evolution and parameterized explosions, the ...

The Karlsruhe Astrophysical Database of Nucleosynthesis in Stars Project - Status and Prospects [PDF]

open access: yes, 2014
The KADoNiS (Karlsruhe Astrophysical Database of Nucleosynthesis in Stars) project is an astrophysical online database for cross sections relevant for nucleosynthesis in the s process and the γ process. The s-process database (http://www.kadonis.org) was

STELLAR NUCLEOSYNTHESIS IN THE HYADES OPEN CLUSTER [PDF]

open access: yesThe Astrophysical Journal, 2009
We report a comprehensive light element (Li, C, N, O, Na, Mg, and Al) abundance analysis of three solar-type main sequence (MS) dwarfs and three red giant branch (RGB) clump stars in the Hyades open cluster using high-resolution and high signal-to-noise spectroscopy.

Initial Shock Waves for Explosive Nucleosynthesis in Type II Supernova [PDF]

open access: yes, 1998
We have performed 1-dimensional calculations for explosive nucleosynthesis in collapse-driven supernova and investigated its sensitivity to the initial form of the shock wave. We have found the tendency that the peak temperature becomes higher around the

Stellar Evolution and Convection in 3D Hydrodynamic Simulations of a Complete Burning Phase

open access: yesGalaxies
Our understanding of stellar evolution and nucleosynthesis is limited by the uncertainties coming from the complex multi-dimensional processes in stellar interiors, such as convection and nuclear burning. Three-dimensional stellar models can improve this
