Explosive Nucleosynthesis

, 2022
Cosmic nucleosynthesis had been one of INTEGRAL’s major science targets. The SPI spectrometer delivered important measurements, both from targets of opportunity in the form of stellar explosions and their shortlived radionuclides, and from cumulative emission of long-lived radioactive isotopes. We review the lessons learned on explosive nucleosynthesis

Fusion reactions induced by radioactive beams: the 18F(p,α)15O case

EPJ Web of Conferences, 2017
Gamma ray astronomy has made big strides in the last decades paving the way to a better understanding of explosive nucleosynthesis. In particular, crucial information on novae nucleosynthesis is linked to the abundance of the 18F isotope, which might be ...

Proton-rich nucleosynthesis and nuclear physics [PDF]

, 2012
Although the detailed conditions for explosive nucleosynthesis are derived from astrophysical modeling, nuclear physics determines fundamental patterns in abundance yields, not only for equilibrium processes. Focussing on the nu p- and the gamma-process,

Comparison of the Core-collapse Evolution of Two Nearly Equal-mass Progenitors

The Astrophysical Journal, 2023
We compare the core-collapse evolution of a pair of 15.8 M _☉ stars with significantly different internal structures, a consequence of the bimodal variability exhibited by massive stars during their late evolutionary stages.

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova

The Astrophysical Journal, 2023
Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

Final stages of massive stars. SN explosion and explosive nucleosynthesis

, 2008
We review the presupernova evolution, the explosion and the explosive nucleosynthesis of massive stars in the range 11–120 M๏. We mainly focus on the advanced evolutionary phases prior to the explosion, i.e.

Impact of Nuclear Reaction Rate Uncertainties on Type I X-Ray Burst Nucleosynthesis: A Monte Carlo Study

The Astrophysical Journal
Type I X-ray bursts are thermonuclear flashes on the surface of accreting neutron stars, involving hundreds of nuclei and thousands of reactions with larger uncertainties in reaction rates. To investigate the impact of nuclear reaction rate uncertainties

Neutrinos and Heavy Element Nucleosynthesis

, 2023
This chapter discusses three nucleosynthesis processes involved in producing heavy nuclei beyond the iron group that are influenced or shaped by neutrino interactions: the v process, the vp process and the r process.

The future of Genesis science

Meteoritics &Planetary Science, Volume 54, Issue 5, Page 1092-1114, May 2019., 2019
Abstract Solar abundances are important to planetary science since the prevalent model assumes that the composition of the solar photosphere is that of the solar nebula from which planetary materials formed. Thus, solar abundances are a baseline for planetary science.
