31. Theories of nucleosynthesis are tested by calculating isotope abundances and comparing those results with observed results. 32. Many new aspects of nucleosynthesis have been discovered from the isotopic ratios within the stardust grains. 33. He also studied the nucleosynthesis in stars and supernovae, and the cosmic abundances of nuclides. 34. Potassium comes only from supernova nucleosynthesis . 35. This is referred to as the deuterium bottleneck, a restriction on the timeline for nucleosynthesis . 36. Thereafter, nucleosynthesis produced the elemental abundance of the early Universe . ( See also nucleocosmochronology .) 37. As has been emphasized, the beta-decays are the slowest processes occurring in explosive nucleosynthesis . 38. :: No, no, this is about heavier elements and evolution after big bang nucleosynthesis . 39. That said, baryon-to-photon ratio does play a role in big bang nucleosynthesis . 40. Germanium is created by stellar nucleosynthesis , mostly by the s-process in asymptotic giant branch stars.
