Nucleosynthesis Predictions and High-Precision Deuterium Measurements
Universe, 2017 Two new high-precision measurements of the deuterium abundance from absorbers along the line of sight to the quasar PKS1937–1009 were presented. The absorbers have lower neutral hydrogen column densities (N(HI) ≈ 18 cm − 2 ) than for previous ...

Positron accumulations from stellar nucleosynthesis
Frontiers in Astronomy and Space SciencesThe predominant fusion chain in stellar nucleosynthesis produces positron and neutrino byproducts in equal amounts. An extremely high neutrino flux can be directly measured, but the unobservable, yet equally high flux of positrons is traditionally ...

Physical Conditions for Synthesis of Sc, Ti, and V in Neutrino-driven Supernovae
The Astrophysical JournalWe present the results of simulations of nucleosynthesis in a core-collapse supernova including the neutrino process. Using the Si layer of a 13 M _⊙ zero-metal progenitor as the initial composition, we calculate the nucleosynthesis by adopting the ...

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