Production of 44Ti and Iron-group Nuclei in the Ejecta of 3D Neutrino-driven Supernovae

The Astrophysical Journal Letters, 2023
The radioactive isotopes ^44 Ti and ^56 Ni are important products of explosive nucleosynthesis, which play a key role in supernova (SN) diagnostics and have been detected in several nearby young SN remnants.

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.

Dust formation and evolution in the ejecta of core-collapse supernovae [PDF]

, 2015
Observations of local supernovae over the past couple of decades have reported the presence of dust in the ejecta. The dust masses inferred from observations in mid-infrared and submillimeter wavelengths differ by a factor of 10^2 to 10^4 The composition

Nucleosynthesis of Binary-stripped Stars

The Astrophysical Journal, 2023
The cosmic origin of the elements, the fundamental chemical building blocks of the universe, is still uncertain. Binary interactions play a key role in the evolution of many massive stars, yet their impact on chemical yields is poorly understood.

How do atomic code uncertainties affect abundance measurements in the intracluster medium?

Astronomische Nachrichten, Volume 341, Issue 2, Page 203-209, February 2020., 2020
Abstract Accurate chemical abundance measurements of X‐ray‐emitting atmospheres pervading massive galaxies, galaxy groups, and clusters provide essential information on the star formation and chemical enrichment histories of these large‐scale structures.

Nucleosynthesis in Stellar Explosions [PDF]

, 1984
The final evolution and explosion of stars from 10 M⊙ to 106 M⊙ are reviewed with emphasis on factors affecting the expected nucleosynthesis. We order our paper in a sequence of decreasing mass. If, as many suspect, the stellar birth function was peaked towards larger masses at earlier times (see e.g., Silk 1977; but also see Palla, Salpeter, and ...

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 ...
