Its existence is revealed through an infrared brightening, an optical dimming, or a blue-red emission-line profile asymmetry. To investigate how the dust location and amount impact observations, we computed ultraviolet-to-optical spectra of interacting and standard, noninteracting Type II SNe using state-of-the-art models -- for simplicity we adopted 0.1micron silicate grains. These models account for the full ejecta and treat both radioactive decay and shock power that arises from interaction of the ejecta wi","authors_text":"Arkaprabha Sarangi, D.
