Nucleosynthesis Predictions and High-Precision Deuterium Measurements

open access: yesUniverse, 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 ...

r -process nucleosynthesis from matter ejected in binary neutron star mergers [PDF]

open access: yes, 2017
When binary systems of neutron stars merge, a very small fraction of their rest mass is ejected, either dynamically or secularly. This material is neutron-rich and its nucleosynthesis provides the astrophysical site for the production of heavy elements ...

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

open access: yesEPJ 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.

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

open access: yesGalaxies
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).
