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 …

After the Big Bang, production of heavy elements in the early Universe takes place starting
from the formation of the first stars, their evolution, and explosion. The first supernova …

How massive stars die—what sort of explosion and remnant each produces—depends
chiefly on the masses of their helium cores and hydrogen envelopes at death. For single …

In the framework of the ESO Large Programme “First Stars”, very high-quality spectra of
some 70 very metal-poor dwarfs and giants were obtained with the ESO VLT and UVES …

We present new nucleosynthesis yields as functions of the stellar mass, metallicity, and
explosion energy (corresponding to normal supernovae and hypernovae). We apply the …

To compare the chemistries of stars in the Milky Way dwarf spheroidal (dSph) satellite
galaxies with stars in the Galaxy, we have compiled a large sample of Galactic stellar …

This article addresses three of the four nucleosynthesis processes involved in producing
heavy nuclei beyond Fe (with a main focus on the r-process). Opposite to the fourth process …

Long γ-ray bursts are associated with energetic, broad-lined, stripped-envelope
supernovae, and as such mark the death of massive stars. The scarcity of such events …

Abstract The Kelvin-Helmholtz cooling epoch, lasting tens of seconds after the birth of a
neutron star in a successful core-collapse supernova, is accompanied by a neutrino-driven …
