Disc fading is the hypothesis that star-forming spiral galaxies can transition into passive lenticular galaxies by ceasing star formation and having the light from the disc fade, as bright, massive blue stars die out. This paper quantifies the contribution such mechanisms might have by comparing predictions from dynamical models (generated by MagRite) with SAMI Galaxy Survey data. These models show that even fairly extreme disc fading scenarios (instant cessation of star formation) can only explain part of the observed decrease in galaxy spin.
