The rapid neutron-capture process needed to build up many of the elements heavier than iron seems to take place primarily in neutron-star mergers, not supernova explosions.

Calculation of atomic properties of superheavy elements Z=110–112 and their ions
We calculate the spectra, electric dipole transition rates and isotope shifts of the super heavy elements Ds (Z=110), Rg (Z=111) and Cn (Z=112) and their ions. These calculations were performed usingExpand

Fusion Energy Output Greater than the Kinetic Energy of an Imploding Shell at the National Ignition Facility.
TLDR
Time dependent low mode asymmetries that limited further progress of implosions have now been controlled, leading to an increased compression of the hot spot, resulting in hot spot areal density and stagnation pressure never before achieved in a laboratory experiment. Expand

TLDR
Spectra of a neutron star merger are unlike other astronomical transients and demonstrate rapid evolution of the source and Kilpatrick et al. show how these observations can be explained by an explosion known as a kilonova, which produces large quantities of heavy elements in nuclear reactions.
