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.
Atd= 10 Mpc, the brightest r-process lines remain detectable by GammaTPC and GRAMS, and are marginally above the e- ASTROGAM threshold

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