We present non-local thermodynamic equilibrium time-dependent radiative transfer simulations of pair-instability supernovae (PISNe) stemming from red-supergiant (RSG), blue-supergiant and Wolf-Rayet star rotation-free progenitors born in the mass range 160-230 M, at 10−4 Z. Although subject to uncer...
