Notes. Both the dust and type Ia SNe trace the stellar distribution with the density profile approximated by the Sérsic model. The two rightmost columns list the relevant scaling relations used to estimate the parameters based on the assumed stellar mass M★ = 1010.5 M⊙. Subscripts {d, ★, Ia} denote dust, stars, and type Ia SNe; Re is the effective radius of the Sérsic density profile. aHyde & Bernardi (2009), bSmith et al. (2012).
