| 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.
