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) …

Within the Local Universe galaxies can be studied in great detail star by star, and here we
review the results of quantitative studies in nearby dwarf galaxies. The color-magnitude …

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 …

Nucleosynthesis in the s process takes place in the He-burning layers of low-mass
asymptotic giant branch (AGB) stars and during the He-and C-burning phases of massive …

The content of neutron-capture (trans-iron-peak) elements in the low-metallicity Galactic
halo varies widely from star to star. The differences are both in bulk amount of the neutron …

We present radial velocities, equivalent widths, model atmosphere parameters, and
abundances or upper limits for 53 species of 48 elements derived from high resolution …

We present homogeneous abundance analysis of over 20 elements for 385 very metal-poor
(VMP) stars based on the LAMOST survey and follow-up observations with the Subaru …

We present a homogeneous chemical abundance analysis of 16 elements in 190 metal-
poor Galactic halo stars (38 program and 152 literature objects). The sample includes 171 …

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 …

We describe the construction of a database of extremely metal-poor (EMP) stars in the
Galaxy. Our database contains detailed elemental abundances, reported equivalent widths …
