Constraints on the Strength of Primordial Magnetic Fields from Big Bang Nucleosynthesis Revisited
Baolian Cheng, Angela V. Olinto, David N. Schramm +1
In this paper, we revisit in detail the effects of primordial magnetic fields on big bang nucleosynthesis (BBN) including a discussion of the magnetic field geometry and the anomal…
The Local Abundance of He: A Confrontation Between Theory and Observation
Sean T. Scully, Michel Casse, Keith A. Olive +3
Determinations of the \he3 concentrations in Galactic matter serve to impose interesting and important constraints both on cosmological models and on models of Galactic chemical ev…
Constraints on the Strength of a Primordial Magnetic Field from Big Bang Nucleosynthesis
Baolian Cheng, David N. Schramm, James W. Truran
The effects of magnetic fields on Big Bang Nucleosynthesis(BBN) have been calculated, and the impact on the abundances of the light elements have been investigated numerically. An…
Interaction Rates at High Magnetic Field Strengths and High Degeneracy
Baolian Cheng, David N. Schramm, James W. Truran
In this paper, we have derived the the effects of strong magnetic fields on nucleon and particle reaction rates of astrophysical significance. We have explored the s…
