The Influence of Nuclear Reactions and Nuclear Structure in Astrophysics
EPJ Web of Conferences, 2017 Nuclear reactions play an important role for the energy production and the nucleosynthesis in stars. New facilities, able to accelerate radioactive nuclei or high-intensity stable beams have allowed us to measure in the laboratory reactions involving ...

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

NITROGEN ISOTOPES IN ASYMPTOTIC GIANT BRANCH CARBON STARS AND PRESOLAR SiC GRAINS: A CHALLENGE FOR STELLAR NUCLEOSYNTHESIS [PDF]
, 2013 Isotopic ratios of C, N, Si, and trace heavy elements in presolar SiC grains from meteorites provide crucial constraints to nucleosynthesis. A long-debated issue is the origin of the so-called A+B grains, as of yet no stellar progenitor thus far has been

The NuGrid AGB Evolution and Nucleosynthesis Data Set
Universe, 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

Nucleosynthesis in AGB stars traced by oxygen isotopic ratios - I. Determining the stellar initial mass by means of the 17O/18O ratio [PDF]
, 2016 Aims. We seek to investigate the 17O/18O ratio for a sample of AGB stars containing M-, S-, and C-type stars. These ratios are evaluated in relation to fundamental stellar evolution parameters: the stellar initial mass and pulsation period.

Fundamentals of stellar evolution and nucleosynthesis [PDF]
EPJ Web of ConferencesThe theory of stellar structure and evolution plays a pivotal role in modern astrophysics. Stellar evolution calculations are used to determine the ages and, to a lesser extent, distances of stars, which are critical to our knowledge of the history and ...
