The light curves of supernovae and other luminous transients are often powered by the decay of radioactive isotopes synthesized in the explosion. In common events, the dominant isotope is 56Ni, however recent theoretical studies have suggested that there may be classes of ``peculiar" transients powered by other radionuclides. For example, the thermonuclear explosion of a degenerate helium shell on the surface of a white dwarf can eject material rich in radioactive 52Fe and 48Cr, leading to an unusually dim and rapidly evolving supernova. In neutron star mergers, dynamically ejected material can undergo R-process nucleosynthesis, with the subsequent decay also energizing an under-luminous transient. Observational surveys are beginning to probe the parameter space of such dim, brief and rare supernovae. I will discuss recent simulations of the explosive nucleosynthesis and radiation physics which attempt to model the production, transport and thermalization of radioactive decay products, and determine how they are reprocessed into the optical light curves and spectra that we observe on earth.
