Nucleosynthesis in Supernovae [PDF]
Physical Review Letters, 1999 Core collapse supernovae are dominated by energy transport from neutrinos. Therefore, some supernova properties could depend on symetries and features of the standard model weak interactions. The cross section for neutrino capture is larger than that for

Unveiling the dynamics of little-bang nucleosynthesis. [PDF]
Nat CommunHigh energy nuclear collisions produce light (anti-)nuclei from the quark-gluon plasma via little-bang nucleosynthesis. Here the authors study the microscopic dynamics of little-bang nucleosynthesis producing deuterons and tritons.

Spectroscopic identification of r-process nucleosynthesis in a double neutron-star merger [PDF]
Nature, 2017 The merger of two neutron stars is predicted to give rise to three major detectable phenomena: a short burst of γ-rays, a gravitational-wave signal, and a transient optical–near-infrared source powered by the synthesis of large amounts of very heavy ...

Fast neutrino flavor conversion, ejecta properties, and nucleosynthesis in newly-formed hypermassive remnants of neutron-star mergers [PDF]
Physical Review D, 2020 Neutrinos emitted in the coalescence of two neutron stars affect the dynamics of the outflow ejecta and the nucleosynthesis of heavy elements. In this work, we analyze the neutrino emission properties and the conditions leading to the growth of flavor ...

Nucleosynthesis Without a Computer [PDF]
International Journal of Theoretical Physics, 2003 I derive completely analytically the time evolution and final abundances of the light elements (up to Be-7) formed in the big-bang nucleosynthesis.This highlights an interesting physics taking place during the formation of light elements in the early ...

Explosive Nucleosynthesis: Prospects [PDF]
Physics Reports, 1999 Explosive nucleosynthesis is a combination of the nuclear physics of thermonuclear reactions, and the hydrodynamics of the plasma in which the reactions occur. It depends upon the initial conditions---the stellar evolution up to the explosive instability,

Neutron Star Mergers and Nucleosynthesis of Heavy Elements [PDF]
Annual Review of Nuclear and Particle Science, 2017 The existence of neutron star mergers has been supported since the discovery of the binary pulsar and the observation of its orbital energy loss, consistent with General Relativity.

Matter and Radiation at Extremes, 2019 With the much-anticipated multi-petawatt (PW) laser facilities that are coming online, neutron sources with extreme fluxes could soon be in reach. Such sources would rely on spallation by protons accelerated by the high-intensity lasers.

Duration of Nucleosynthesis [PDF]
Physical Review Letters, 1960 In a recent Letter on a determination of the age of the elements, Reynolds[1] reported the important discovery of isotopically anomalous xenon in the stony meteorite Richarton. The isotopes which appear to occur in significant excess over atmospheric xenon are Xe128, Xe129, Xe130, and Xe131, with the Xe129 dominant by an order of magnitude.
