Linking neutrino oscillations to the nucleosynthesis of elements
EPJ Web of Conferences, 2016 Neutrino interactions with matter play an important role in determining the nucleosynthesis outcome in explosive astrophysical environments such as core-collapse supernovae or mergers of compact objects.

Magic nuclei at explosive dynamo activity
EPJ Web of Conferences, 2016 Explosive nucleosynthesis at conditions of magnetorotational instabilities is considered for iron group nuclides by employing arguments of nuclear statistical equilibrium.

EXPERIMENTAL FOUNDATIONS OF EXPLOSIVE NUCLEOSYNTHESIS [PDF]
Le Journal de Physique Colloques, 1975 Laboratory studies of nuclear reaction rates relevant to carbon, oxygen and silicon burning in explosive nucleosynthesis will be discussed. Emphasis will be placed on the role of excited nuclear states in the reactions involved.

Explosive nucleosynthesis and beyond: Energy generation in supernovae from massive progenitors [PDF]
EPJ Web of ConferencesMassive stars (initial mass ≳10M⊙, where M⊙ is the mass of the Sun) end their life through violent explosions known as core-collapse supernovae, which are supposed to be among the brightest events of the universe.

Improving explosive nucleosynthesis models via (n,alpha) measurements
, 2001 In explosive environments, (gamma,alpha) reactions constitute some of the most important links in the nucleosynthesis chains. However. it is very unlikely that the rates for most of these reactions will be determined by direct experiments and these rates

Ar+ ArH+ Reactive Collisions of Astrophysical Interest: The Case of 36Ar
ChemPhysChem, Volume 24, Issue 20, October 17, 2023., 2023 A complete theoretical investigation of the 36Ar+36ArH+ reactive collision involving the most abundant Argon isotope in the interstellar medium. Abstract The reactive collision between 36Ar and the 36ArH+ species has been investigated by means of quantum mechanical (QM), quasiclassical trajectories (QCT) and statistical quantum mechanical (SQM ...

Geophysical Research Letters, Volume 50, Issue 4, 28 February 2023., 2023 Abstract We employed MC‐ICP‐MS to measure the mass‐dependent Ca isotope compositions of Vesta‐related meteorites. Eucrites and diogenites show distinct Ca isotope compositions, which is caused by crystallization of isotopically heavy orthopyroxene. The Ca isotope data support a model where the two lithologies are linked, where the diogenites, mainly ...

Possible Control of Earth's Boron Budget by Metallic Iron
Geophysical Research Letters, Volume 49, Issue 10, 28 May 2022., 2022 Abstract Boron is considered a principal tracer for crustal recycling into the depleted mantle, and high boron anomalies and isotopically light boron (10B) in mantle‐derived samples have been interpreted as the result of subduction. Using density functional theory, we predict that boron behavior changes from lithophile to siderophile, with the ...
