Neutrino at Different Epochs of the Friedmann Universe

open access: yesUniverse
At 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

open access: yesEPJ 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 ...

Big Bang Nucleosynthesis with f(R) Gravity Scalarons and Astrophysical Consequences

open access: yesThe Astrophysical Journal
f ( R ) gravity is one of the serious alternatives of general relativity with a large range of astronomical consequences. In this work, we study Big Bang nucleosynthesis (BBN) in f ( R ) gravity theory.

The Origins of Lithium Enhancement in Polluted White Dwarfs

open access: yesThe Astrophysical Journal
The 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.
