Supernova nucleosynthesis - Wikipedia
Supernova nucleosynthesis is the nucleosynthesis of chemical elements in supernova explosions.
Nucleosynthesis – How Elements Are Made - Science Notes and …
Jun 22, 2022 · Supernova nucleosynthesis: A supernova produces many intermediate-mass elements between oxygen and rubidium. Largely, this involves rapid neutron-capture, although rapid proton-capture (rp-process) may occur, too.
Populating the periodic table: Nucleosynthesis of the elements
Feb 1, 2019 · This nucleosynthesis takes just a few seconds, explosively destroying the white dwarf as a type Ia supernova and ejecting its entire mass into the surrounding galaxy. Because this type of supernova does not produce free neutrons, they do not synthesize any elements beyond the iron peak.
oobservations of gamma rays emitted by supernova nucleosynthesis can provide important constraints on theoretical models ocurrently the deepest probe of supernova ejecta (gravitational waves would be deeper)

As a massive star collapses, it produces a shockwave that can induce fusion in the star’s outer shell. These fusion reactions create new atomic nuclei in a process called nucleosynthesis. Supernovae are considered one of the original sources …
Nucleosynthesis in Supernovae The explosion of a core-collapse supernova leads to ejection of the star’s mantle, and thus to substantial enrichment of the interstellar medium with the major burning products of hydrostatic equilibirium: 4He, 12C, 16O, 20Ne, etc. As was described in …
DOE Explains...Nucleosynthesis | Department of Energy
Scientists believe that violent neutron-rich environments such as the merger of two neutron start or supernovae produce the heaviest naturally occurring elements, including gold, platinum, and uranium. Optical observations of neutron star mergers provide evidence of possible nucleosynthesis of heavy elements.

Mar 26, 2018 · We present the status and open problems of nucleosynthesis in supernova explosions of both types, responsible for the production of the intermediate mass, Fe-group and heavier elements (with the exception of the main s-process).
Fred Hoyle and Supernova Nucleosynthesis
A rarer process, supernova nucleosynthesis, occurs within exploding stars and is responsible for creating elements numbered from 6 (carbon) to 28 (nickel) on the periodic table, according to first reports detailed by Sir Fred Hoyle in 1954.
Supernova nucleosynthesis
Mar 25, 1997 · Stars with masses roughly ten times the mass of the sun die in violent explosions known as Type II supernovae. Element formation occurs in such massive stars both during the pre-explosion evolution and during the explosion itself.
