From nuclei to the cosmos: tracing heavy-element production with the oldest stars
A Frebel - Annual Review of Nuclear and Particle Science, 2018 - annualreviews.org
Understanding the origin of the elements has been a decades-long pursuit, with many open
questions remaining. Old stars found in the Milky Way and its dwarf satellite galaxies can …

Populating the periodic table: Nucleosynthesis of the elements
JA Johnson - Science, 2019 - science.org
Elements heavier than helium are produced in the lives and deaths of stars. This Review
discusses when and how the process of nucleosynthesis made elements. High-mass stars …

Nitrogen enhancements 440 Myr after the big bang: supersolar N/O, a tidal disruption event, or a dense stellar cluster in GN-z11?
Recent observations of GN-z11 with JWST/NIRSpec revealed numerous oxygen, carbon,
nitrogen, and helium emission lines at z= 10.6. Using the measured line fluxes, we derive …

An absolutely calibrated Teff scale from the infrared flux method-Dwarfs and subgiants
Various effective temperature scales have been proposed over the years. Despite much
work and the high internal precision usually achieved, systematic differences of order 100 K …

Nucleosynthesis and evolution of massive metal-free stars
A Heger, SE Woosley - The Astrophysical Journal, 2010 - iopscience.iop.org
The evolution and explosion of metal-free stars with masses 10–100 M☉ are followed, and
their nucleosynthetic yields, light curves, and remnant masses determined. Such stars would …
