Neutrinos and the Supernova Origin of the Elements

, 2000
Intense fluxes of neutrinos are emitted by the hot neutron star produced in a supernova. The electron neutrino and antineutrino capture reactions on neutrons and protons, respectively, provide heating to drive a wind from the hot neutron star.

Neutrinos and Primordial Nucleosynthesis

, 2004
The importance of the Big Bang Nucleosynthesis (BBN) as a unique tool for studying neutrino properties is discussed, and the recent steps towards a self-consistent and robust handling of the weak reaction decoupling from the thermal bath as well as of ...

Structure effects of 20N in elemental abundance estimations during explosive nucleosynthesis [PDF]

EPJ Web of Conferences
Most nuclei far from the valley of stability, and typically near the drip lines, exhibit exotic features that have challenged our current understanding of nuclear structure.

The new p-process database of KADoNiS [PDF]

, 2010
The KADoNiS (Karlsruhe Astrophysical Database of Nucleosynthesis in Stars) project is an online database (www.kadonis.org) for cross sections relevant to the s-process and the p-process. The first version was an updated sequel to the previous Bao et al.

Neutrino Interactions in the Outflow from Gamma-Ray Burst Accretion Disks

, 2004
We examine the composition of matter as it flows away from gamma ray burst accretion disks, in order to determine what sort of nucleosynthesis may occur.

From the s-Process to the i-Process: A New Perspective on the Chemical Enrichment of Extrinsic Stars

Galaxies
Separating stars enriched in the s- and r-processes of nucleosynthesis is usually achieved by analyzing the element ratios of s-process elements (like Ba or La) to r-process elements (like Eu).

Explosive Nucleosynthesis

, 2022
Cosmic nucleosynthesis had been one of INTEGRAL’s major science targets. The SPI spectrometer delivered important measurements, both from targets of opportunity in the form of stellar explosions and their shortlived radionuclides, and from cumulative emission of long-lived radioactive isotopes. We review the lessons learned on explosive nucleosynthesis

Recent Advances in Understanding R-Process Nucleosynthesis in Metal-Poor Stars and Stellar Systems

Universe
The rapid neutron-capture process (r-process) is responsible for the creation of roughly half of the elements heavier than iron, including precious metals like silver, gold, and platinum, as well as radioactive elements such as thorium and uranium ...
