R-process Nucleosynthesis of Subminimal Neutron Star Explosions
The Astrophysical Journal, 2023 We show that a minimum-mass neutron star undergoes delayed explosion after mass removal from its surface. We couple the Newtonian hydrodynamics to a nuclear reaction network of ∼4500 isotopes to study the nucleosynthesis and neutrino emission during the ...

Experimental Nuclear Astrophysics With the Light Elements Li, Be and B: A Review
Frontiers in Astronomy and Space Sciences, 2021 Light elements offer a unique opportunity for studying several astrophysical scenarios from Big Bang Nucleosynthesis to stellar physics. Understanding the stellar abundances of light elements is key to obtaining information on internal stellar structures

Pediatric Blood &Cancer, Volume 71, Issue 11, November 2024.Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...

Nucleosynthesis in Thermonuclear Supernovae [PDF]
, 2017 The explosion energy of thermonuclear (Type Ia) supernovae is derived from the difference in nuclear binding energy liberated in the explosive fusion of light 'fuel' nuclei, predominantly carbon and oxygen, into more tightly bound nuclear 'ash' dominated by iron and silicon group elements.

Challenges and Requirements in High-Precision Nuclear Astrophysics Experiments
Universe, 2022 In the 21th century astronomical observations, as well as astrophysical models, have become impressively precise. For a better understanding of the processes in stellar interiors, the nuclear physics of astrophysical relevance—known as nuclear ...

Neutrinos and Primordial Nucleosynthesis [PDF]
Nuclear Physics B - Proceedings Supplements, 2005 The importance of the Big Bang Nucleosynthesis (BBN) as a unique tool for studying neutrino properties is discussed, and the recent steps towards a self-consistent and robust handling of the weak reaction decoupling from the thermal bath as well as of the neutrino reheating following the e+e- annihilation are summarized. We also emphasize the important

Geostandards and Geoanalytical Research, Volume 48, Issue 2, Page 331-343, June 2024.Key Points Corrected for the Earth's magnetic field, the SHRIMP's IMF depends on the mineral species, not the chemical composition. The IMF arises from the force constant difference between "hard" and "soft" bonds, which is characteristic of each mineral. This permitted the calculation of IMF‐correction factors for most common Mg‐bearing minerals.

Neutron-induced nucleosynthesis [PDF]
, 1996 Neutron--induced nucleosynthesis plays an important role in astrophysical scenarios like in primordial nucleosynthesis in the early universe, in the s--process occurring in Red Giants, and in the $\alpha$--rich freeze--out and r--process taking place in supernovae of type II.
