While transient astronomy is often associated with young, rapidly evolving sources, there is a subset of dusty, old supernovae (SNe) that are quite valuable to our understanding of SN explosions and their progenitor systems. The near-and mid-IR wavelengths span the peak of the thermal emission from such dust and are best to characterize the dust in these systems. Yet the phase space of existing observations (in terms of dust temperature and SN age) remains relatively unpopulated owing to the combined low sensitivity and/or limited IR wavelength coverage of existing telescopes. JWST offers a unique opportunity to detect a large sample of these SNe at long wavelengths and late times. With literally thousands of SNe having exploded in nearby (< 200 Mpc) galaxies over the past 50-100 years, an archival study stands to yield a bonanza of low-hanging fruit. Here we propose an Archival Research (AR) program …
