Journal ArticleDOI
Primordial nucleosynthesis redux
TL;DR: In this article, the abundances of the light elements were recalculated within the framework of primordial nucleosynthesis in the standard hot big band model, in order to estimate the primordial abundances.
Journal ArticleDOI
Primordial nucleosynthesis: Theory and observations
TL;DR: In this paper, the cosmology and physics underlying primordial nucleosynthesis were reviewed and current observational data was surveyed in order to compare the predictions of Big Bang Nucleosynthesis with the inferred primordial abundances.
Journal ArticleDOI
Halo Star Lithium Depletion
TL;DR: In this article, the mass-dependent angular momentum loss law inferred from open cluster studies produces a nearly flat plateau, unlike previous models that exhibited a downward curvature for hotter temperatures in the 7Li-Teff plane.
Journal ArticleDOI
Direct X-ray Constraints on Sterile Neutrino Warm Dark Matter
TL;DR: In this paper, the authors used the diffuse X-ray spectrum (total minus resolved point source emission) of the Andromeda galaxy to constrain the rate of sterile neutrino radiative decay.
Journal ArticleDOI
Time variation of fundamental constants, primordial nucleosynthesis, and the size of extra dimensions.
TL;DR: Requiring the yield of primordial sup4He to be within acceptable limits, it is found that in ten-dimensional superstring models the size of the extra dimensions during primordial nucleosynthesis must have been within 0.5% of their current value.
