Dust and the intrinsic spectral index of quasar variations: Hints of finite stress at the innermost stable circular orbit
We present a study of 9 242 spectroscopically confirmed quasars with multiepoch ugriz photometry from the SDSS Southern Survey. By fitting a separable linear model to each quasar's spectral variations, we decompose their five-band spectral energy distributions into variable (disc) and non-varia...
