Impact of AGB Stars on the Chemical Evolution of Neutron-Capture Elements
Universe, 2022 In this review, we discuss the impact of s-process nucleosynthesis in asymptotic giant branch stars on the enrichment of heavy elements. We review the main steps made on this subject in the last 40 years and discuss the importance of modelling the ...

General relativistic effects on neutrino-driven wind from young, hot neutron star and the r-process nucleosynthesis [PDF]
, 1999 Neutrino-driven wind from young hot neutron star, which is formed by supernova explosion, is the most promising candidate site for r-process nucleosynthesis.

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 ...

The NuGrid AGB Evolution and Nucleosynthesis Data Set
Universe, 2022 Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as C, N and F, and half of the elements heavier than Fe via the slow neutron

Fast neutrino flavor conversion, ejecta properties, and nucleosynthesis in newly-formed hypermassive remnants of neutron-star mergers [PDF]
, 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 ...

Structure formation cosmic rays: Identifying observational constraints [PDF]
Serbian Astronomical Journal, 2005 Shocks that arise from baryonic in-fall and merger events during the structure formation are believed to be a source of cosmic rays. These "structure formation cosmic rays" (SFCRs) would essentially be primordial in composition, namely, mostly made of ...

Mergers of Binary Neutron Star Systems: A Multimessenger Revolution
Frontiers in Astronomy and Space Sciences, 2021 On August 17, 2017, less than two years after the direct detection of gravitational radiation from the merger of two∼30 M⊙ black holes, a binary neutron star merger was identified as the source of a gravitational wave signal of ∼100 s duration that ...

Nucleosynthesis in magneto-rotational supernovae [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We present the nucleosynthesis of magneto-rotational supernovae (MR-SNe) including neutrino-driven and magneto-rotational-driven ejecta based, for the first time, on two-dimensional simulations with accurate neutrino transport. The models analysed here
