Dynamic Screening in Thermonuclear Reactions
It has recently been argued that there are no dynamic screening corrections to Salpeter’s enhancement factor in thermonuclear reactions, in the weak-screening limit. The arguments used were: 1) The Gibbs probability distribution is factorable into two parts, one of which, exp(−β∑ eiej/rij) (β = 1/kBT ), is independent of velocity space; and 2) The enhancement factor is w = 1 + βeZ1Z2〈φ〉 with 〈φ...
متن کاملElectron screening effect on stellar thermonuclear fusion
We study the impact of plasma correlation effects on nonresonant thermonuclear reactions for various stellar objects, namely in the liquid envelopes of neutron stars, and the interiors of white dwarfs, low-mass stars, and substellar objects. We examine in particular the effect of electron screening on the enhancement of thermonuclear reactions in dense plasmas within and beyond the linear mixin...

متن کاملBound Electron Screening Corrections to Reactions in Hydrogen Burning Processes
We estimate the bare astrophysical S-factor(Sb(E)) of reactions in PP-chains, through a polynomial expression with the adiabatic enhancement factor due to the electron screening. The obtained Sb is significantly different from the simple extrapolation from high energy data, however Sb at zero incident energy is in agreement with the results of a recent R-matrix analysis.
متن کاملScreening in Thermonuclear Reaction Rates in the Sun
We evaluate the effect of electrostatic screening by ions and electrons on low-Z thermonuclear reactions in the sun. We use a mean field formalism and calculate the electron density of the screening cloud using the appropriate density matrix equation of quantum statistical mechanics. Because of well understood physical effects that are included for the first time in our treatment, the calculate...
