Time-domain surveys of the past decade have revealed a population of low luminosity transients of stellar origin evolving on months to years timescales including luminous red novae, intermediate luminosity red transients, and, possibly, failed supernovae. These systems evolve from optical to infrared wavelengths as dust forms in the expanding ejecta, remaining bright infrared sources for years. With several new and upcoming infrared surveys (e.g., WINTER, PRIME, SPHEREx, Cryoscope, Roman), we are now squarely in the era of time-domain astrophysics in the infrared. Combined with Rubin, we can study dust and molecule formation in these systems like never before to learn about the progenitor systems that drive these transients as well as the contribution of these transients to the cosmic dust budget.
