Neutrino at Different Epochs of the Friedmann Universe
UniverseAt least two relics of the Big Bang have survived: the cosmological microwave background (CMB) and the cosmological neutrino background (CνB). Being the second most abundant particle in the universe, the neutrino has a significant impact on its evolution

Proton-Induced Reactions of Astrophysical Interest
EPJ Web of Conferences, 2018 A discrepancy exists between the 6Li abundances predicted from big bang nucleosynthesis models and those measured in pre-main sequence stars. To further constrain the predicted abundances of 6Li in these stars, high accuracy measurements are required of ...

First measurement of the 7Li(D, n) astrophysical S-factor in laser-induced full plasma
Physics Letters B, 2023 Nuclear fusion reactions which produce energies and most of the elements in the Universe are the keys to driving the process of the Big Bang nucleosynthesis, as well as the evolution of stars.

Big Bang Nucleosynthesis constraints on f(T,T) gravity
Physics Letters BBig Bang Nucleosynthesis provides us with an observational insight into the very early Universe. Since this mechanism of light element synthesis comes out of the standard model of particle cosmology which follows directly from General Relativity, it is ...

The Origins of Lithium Enhancement in Polluted White Dwarfs
The Astrophysical JournalThe bulk abundances of exoplanetesimals can be measured when they are accreted by white dwarfs. Recently, lithium from the accretion of exoplanetesimals was detected in relatively high levels in multiple white dwarfs.
