Revisiting and Resolving Dusty Massive stars in the Infrared

Driven by our revised understanding on the influence of binary companions in massive star evolution, my research has focused on revisiting the impact of carbon-rich Wolf-Rayet (WC) binaries as early and dominant sources of dust. Although these systems can produce copious amounts of dust, they have been commonly overlooked as significant sources of dust in the ISM of galaxies in the local and early Universe due to the persisting mysteries on their dust formation and the influence of binary companions. In pursuit of this research, I am leading an Early Release Science (ERS) program with the recently launched James Webb Space Telescope (JWST). In this talk, I will present my research program using ground- and space-based infrared (IR) observations to revisit and resolve dusty massive stars.
