Physical Conditions for Synthesis of Sc, Ti, and V in Neutrino-driven Supernovae

The Astrophysical Journal
We 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

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).

Nucleosynthesis in Core-Collapse Supernovae [PDF]

, 2018
The nucleosynthesis which occurs in core-collapse supernovae (CCSN) is one of the most important sources of elements in the universe. Elements from Oxygen through Iron come predominantly from supernovae, and contributions of heavier elements are also ...

Nucleosynthesis in Core-Collapse Supernovae

, 2019
Core-collapse supernovae (CCSNe) are one of the most important nucleosynthesis sites and they hold a key role in the evolution of galaxies. In the explosion, CCSNe eject freshly synthesized iron-group nuclei from explosive burning alongside of ...

Core-collapse supernovae and nucleosynthesis [PDF]

, 1994
I discuss some of the physics that governs the collapse and explosion of a massive star, including issues such as lepton number losses in the infall stage and neutrino heating and convection following the core bounce. I review recent work on the neutrino
