The production of about half of the heavy elements found in nature is assigned to a specific
astrophysical nucleosynthesis process: the rapid neutron-capture process (r process) …

What is the origin of the oxygen we breathe, the hydrogen and oxygen (in form of water
H2O) in rivers and oceans, the carbon in all organic compounds, the silicon in electronic …

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 …

Context. The chemo-physical parametrisation of stellar spectra is essential for
understanding the nature and evolution of stars and of Galactic stellar populations. 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 …

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 …

We present a nearly complete rapid neutron-capture process (r-process) chemical inventory
of the metal-poor ([Fe/H]=− 1.46±0.10) r-process-enhanced ([Eu/Fe]=+ 1.32±0.08) halo star …

A century ago, nuclear physics entered astrophysics, giving birth to a new field of science
referred to as “Nuclear Astrophysics”. With time, it developed at an impressive pace into a …

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 …

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 …
