The origin of deuterium

  title={The origin of deuterium},
  author={R. Epstein and J. Lattimer and D. Schramm},
General nuclear constraints are used to show that deuterium is most likely of pregalactic origin. Big-bang nucleosynthesis is the most plausible source for significant amounts of this isotope, but other, more speculative, sources are not ruled out. 
Interstellar Helium and Deuterium
The importance of helium and deuterium is underlined: both are probably ashes of the primordial nucleosynthesis and represent some of the most abundant elements in the universe. For both elements theExpand
Cosmological deuterium production in non-standard scenarios
Abstract It is widely believed that the cosmic baryon density may be obtained by inferring deuterium abundances in low-metallicity quasar absorption line systems. The implicit assumptions which enterExpand
Big Bang Nucleosynthesis
Abstract Big Bang Nucleosynthesis (BBN) is the synthesis of the light nuclei, Deuterium (D or 2 H), 3 He, 4 He and 7 Li during the first few minutes of the universe. This review concentrates onExpand
Big-bang nucleosynthesis
Latest nucleosynthesis constraints on the baryon density of the universe
Big-bang nucleosynthesis plays a crucial role in constraining big-bang cosmology. Although the uncertainties in the observations of the light elements are governed by systematic effects, firm boundsExpand
Abundances of Deuterium, Nitrogen, and Oxygen toward HZ 43A: Results from the FUSE Mission
We present an analysis of interstellar absorption along the line of sight to the nearby white dwarf star HZ43A. The distance to this star is 68±13 pc, and the line of sight extends toward the northExpand
Deuteronomy and numbers
Four light isotopes - D, ^3He, ^4He and ^7Li - were produced by nuclear reactions a few seconds after the big bang. New measurements of ^3He in the ISM by Gloeckler and Geiss and of deuterium in highExpand
Deuterium concentration in the early Solar System: hydrogen and oxygen isotope study

Big bang nucleosynthesis: fateway to the very early universe
The status of the concordance of the standard model of primordial nucleosynthesis with current observational data is reviewed. It is concluded that at present the standard model is consistent withExpand
The BBN manifesto
Abstract In this manifesto I review the current status of standard big bang nucleosynthesis in light of recent observational data and discuss the importance of near-future observations as directExpand
