Simulations predict time-dependent gamma-ray lines from r-process and iron-peak decays in accretion-induced white dwarf collapse, detectable to ~10 Mpc and absent in neutron star mergers.

In neutron star merger ejecta simulations, coupling in-situ nuclear networks with composition-dependent thermalization and frequency-dependent opacities changes nucleosynthesis yields, delays and reddens early emission, and produces brighter, bluer kilonovae than simplified analytic prescriptions.

Gamma-ray Signatures of r-Process Radioactivity from the Collapse of Magnetized White Dwarfs

Impact of in situ nuclear networks and atomic opacities on neutron star merger ejecta dynamics, nucleosynthesis, and kilonovae
In neutron star merger ejecta simulations, coupling in-situ nuclear networks with composition-dependent thermalization and frequency-dependent opacities changes nucleosynthesis yields, delays and reddens early emission, and produces brighter, bluer kilonovae than simplified analytic prescriptions.
