Recent Advances in Understanding R-Process Nucleosynthesis in Metal-Poor Stars and Stellar Systems

Universe
The rapid neutron-capture process (r-process) is responsible for the creation of roughly half of the elements heavier than iron, including precious metals like silver, gold, and platinum, as well as radioactive elements such as thorium and uranium ...

Universality and variability of the heavy r-process element abundance pattern from a nonequilibrium approach

Frontiers in Astronomy and Space Sciences
A striking feature in the observed chemical composition of the majority of stars is the universality of the relative abundances of the heavy elements, although some outliers exist.

The origins of neutron-capture elements in globular cluster M22

Frontiers in Astronomy and Space Sciences
IntroductionThe chemical abundances of metal poor (MP) stars in globular clusters provide valuable information for constraining their evolutionary scenarios.MethodsUsing both main r-process and weak r-process patterns, we fit the abundances of s-poor ...
