A moving ion in plasma creates a deformed electric potential depending on the ion velocity, which leads to the distinct screening effect compared to the standard static Salpeter formula. In this paper, adopting the test charge method, we explore the dynamical screening effects on big bang nucleosynthesis (BBN). We find that the high temperature in the early universe causes the ion velocity to be faster than the solar condition so that the electric potential is effectively polarized. However… Expand

Experimental evidence of neutrinos produced in the CNO fusion cycle in the Sun.
TLDR
This work provides experimental evidence of the primary mechanism for the stellar conversion of hydrogen into helium in the Universe, and paves the way towards a direct measurement of the solar metallicity using CNO neutrinos. Expand
Screening Effects on Electron Capture Rates and Type Ia Supernova Nucleosynthesis
Type Ia supernovae (SNe Ia) are believed to be a thermonuclear explosion of a white dwarf, but the mass of their progenitors is still an open problem. In near-Chandrasekhar-mass (near-M_Ch) models ofExpand
Screening corrections to electron capture rates and resulting constraints on primordial magnetic fields
We explore screening effects arising from a relativistic magnetized plasma with applications to Big Bang nucleosynthesis (BBN). %Specifically, due to their small magnetic moments, energies ofExpand
Spectral energy distribution of the equilibrium radiation and its asymptotic behavior in ideal gaseous plasmas

The baryon density of the Universe from an improved rate of deuterium burning.
TLDR
Improved cross-sections of the deuterium burning D(p,γ)3He reaction lead to BBN estimates of the baryon density at the 1.6 percent level, in excellent agreement with a recent analysis of the cosmic microwave background. Expand
