s-Processing in Asymptotic Giant Branch Stars in the Light of Revised Neutron-Capture Cross Sections
Universe, 2021 Current AGB stellar models provide an adequate description of the s-process nucleosynthesis that occurs. Nonetheless, they still suffer from many uncertainties related to the modeling of the 13C pocket formation and the adopted nuclear reaction rates ...

Nucleosynthesis in O-Ne-Mg Supernovae [PDF]
, 2007 We have studied detailed nucleosynthesis in the shocked surface layers of an Oxygen-Neon-Magnesium core collapse supernova with an eye to determining if the conditions are suitable for r process nucleosynthesis.

Big bang nucleosynthesis [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 The concordance of standard big bang nucleosynthesis theory and the related observations of the light element isotopes (including some new higher \he4 abundances) will be reviewed. Implications of BBN on chemical evolution, dark matter and constraints on particle properties will be discussed.

Positron Transport and Annihilation in the Galactic Bulge
Galaxies, 2018 The annihilation of positrons in the Milky Way Galaxy has been observed for ∼50 years; however, the production sites of these positrons remains hard to identify.

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 ...

QUÍMICA ESTELAR E ESTRELAS APOCALÍPTICAS: ESTUDO COMPARATIVO
Colloquium Exactarum, 2012 All atoms existing in the Universe, except Hydrogen (H) and helium (He), arise from processes occurring in stars and their evolution. The stars transmute the H and He in other heavier elements through nuclear fusion and its process rolling, filling and ...
