Neutron captures produce the vast majority of abundances of elements heavier than iron in
the Universe. Beyond the classical slow (s) and rapid (r) processes, there is observational …

Binary stars are as common as single stars. Binary stars are of immense importance to
astrophysicists because that they allow us to determine the masses of the stars independent …

To reach a deeper understanding of the origin of elements in the periodic table, we construct
Galactic chemical evolution (GCE) models for all stable elements from C (A= 12) to U (A …

Probing the origin of r-process elements in the universe represents a multidisciplinary
challenge. We review the observational evidence that probes the properties of r-process …

The decomposition of the Solar system abundances of heavy isotopes into their s-and r-
components plays a key role in our understanding of the corresponding nuclear processes …

We search for dynamical substructures in the LAMOST DR3 very metal-poor (VMP) star
catalog. After cross-matching with Gaia DR2, there are∼ 3300 VMP stars with available high …

The heaviest chemical elements are naturally produced by the rapid neutron-capture
process (r-process) during neutron star mergers or supernovae. The r-process production of …

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 …

This compilation is the fourth data release from the R-Process Alliance (RPA) search for r-
process-enhanced stars and the second release based on" snapshot" high-resolution (R∼ …

Mendeleev's introduction of the periodic table of elements is one of the most important
milestones in the history of chemistry, as it brought order into the known chemical and …
