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) …

The rapid neutron capture process (r process) is believed to be responsible for about half of
the production of the elements heavier than iron and contributes to abundances of some …

The r-process nucleosynthesis in core-collapse supernovae (CC-SNe) is studied, with a
focus on the explosion scenario induced by rotation and strong magnetic fields …

We systematically examine how the presence in a binary affects the final core structure of a
massive star and its consequences for the subsequent supernova explosion. Interactions …

We present results of simulations of stellar collapse and explosions in spherical symmetry
for progenitor stars in the 8–range with an O-Ne-Mg core. The simulations were continued …

The astrophysical nature of r-process sites is a long-standing mystery and many probable
sources have been suggested, among them lower-mass core-collapse supernovae (in the …

Core-collapse supernovae are among the most energetic explosions in the universe
marking the catastrophic end of massive stars. In spite of rigorous studies for several …

We have obtained high-resolution, high signal-to-noise near-UV–blue spectra of 22 very
metal-poor stars ([Fe/H]<-2.5) with the Subaru High Dispersion Spectrograph and measured …

We study the late evolution of solar metallicity stars in the transition region between white
dwarf formation and core collapse. This includes the super-asymptotic giant branch (super …

Context. Massive AGB (hereafter super-AGB or SAGB) stars ignite carbon off-center and
have initial masses ranging between $ M_ {\mathrm {up}} $, the minimum initial mass for …
