Experimental Approach to Explosive Nucleosynthesis

Nuclear Physics A, 1992
Abstract Recent development of experimental studies on explosive nucleosynthesis, especially the rapid proton process and the primordial nucleosynthesis were discussed with a stress on unstable nuclei. New development in the experimental methods for the nuclear astrophysics is also discussed which use unstable nuclear beams.

Explosive nucleosynthesis in ONeMg novae

Nuclear Physics A, 1997
Abstract A quasi-analytic study on ONeMg novae is performed to examine explosive nucleosynthesis in wide range of white dwarf and envelope masses. Comparing our results with recent observations enables us to constrain those two parameters. About a half of observed ONeMg novae may have attained high envelope masses such as ∼10−4 M⊙, then obtained high

Explosive Nucleosynthesis in Supernovae and Hypernovae

AIP Conference Proceedings, 2010
We review the properties of supernovae (SNe) as a function of the progenitor’s mass M. (1) 8–10 M⊙ stars are super‐AGB stars and resultant electron capture SNe may be Faint supernovae like Type IIn SN 2008S. (2) 10–13 M⊙ stars undergo Fe‐core collapse to form neutron stars (NSs) and Faint supernovae. (3) 13 M⊙–MBN stars undergo Fe‐core collapse to form

Supernova neutrinos and explosive nucleosynthesis

AIP Conference Proceedings, 2014
Core-collapse supernovae eject huge amount of flux of energetic neutrinos. We studied the explosive nucleosyn-thesis in supernovae and found that several isotopes 7Li, 11B, 92Nb, 138La and 180Ta as well as r-process nuclei are affected by the neutrino interactions.

Explosive Nucleosynthesis in the Galaxy

Nature Physical Science, 1971
The hypothesis that most of the naturally occurring nuclei in the mass range 20≤A≤62 were produced by nuclear detonation in supernova explosions is examined in the context of different galactic histories.

Nucleosynthesis in classical nova explosions

Journal of Physics G: Nuclear and Particle Physics, 2007
Classical novae are fascinating stellar explosions at the crossroads of stellar astrophysics, nuclear physics, and cosmochemistry. In this review, we briefly summarize 30 years of nucleosynthesis studies, with special emphasis on recent advances in nova theory (including multidimensional models) as well as on experimental efforts to reduce nuclear ...

Destruction of26Al in explosive nucleosynthesis

Zeitschrift f�r Physik A Atomic Nuclei, 1986
The26Al(n, p)26Mg reaction has been studied using neutron spectra which closely resembled Maxwell-Boltzmann (M.-B.) distributions with thermal energies ofkT=40 ×10−6, 31 and 71 keV and also forEn=270–350 keV. These energies correspond to stellar temperaturesT9=4.6×10−7, 0.36, 0.82 and 3.1–4.1, whereT9 is in units of 109 K.

Explosive Nucleosynthesis Revisited: Yields

Annual Review of Astronomy and Astrophysics, 1995
Three new, independent projects that provide detailed predictions of nucleosynthesis yields (up to Z = 36) from massive stars are examined and compared. The general agreement is surprisingly good. Preliminary comparison with abundance data, especially for elemental abundances in extreme Population II stars, is promising.

Tabletop Nucleosynthesis Driven by Cluster Coulomb Explosion

Physical Review Letters, 2006
Coulomb explosion of completely ionized (CH4)n, (NH3)n, and (H2O)n clusters will drive tabletop nuclear reactions of protons with 12C6+, 14N7+, and 16O8+ nuclei, extending the realm of nuclear reactions driven by ultraintense laser-heterocluster interaction.

Nucleosynthesis in Aspherical Explosions of Population III Stars

AIP Conference Proceedings, 2008
We present the nucleosynthetic yields of Population III core‐collapse supernovae (SNe) focusing on the cases of hyper‐energetic (Hypernovae, HNe) and hyper‐aspherical (jet‐induced) explosions. We show that (1) the explosions with large energy deposition rate, Ėdep, are observed as GRB‐HNe and their yields can explain the abundances of normal extremely ...
