Abstract: We revisit the state of the light element abundances from big bang nucleosynthesis in early 2024 with particular focus on the derived baryon abundance. We find that the largest differences between the final baryon abundances… read more here.

Abstract: Ancient globular clusters contain multiple stellar populations identified by variations in light element (e.g., C, N, O, Na). Though many scenarios have been suggested to explain this phenomenon, all are faced with challenges when compared… read more here.

Abstract: Light element alloying in iron is required to explain density deficit and seismic wave velocities in Earth’s core. However, the light element composition of the Earth’s core seems hard to constrain as nearly all light… read more here.
