Σ(r)/Σ(R) as function of r with α = 0.2 and ϵ = 0.1 (all stellar parameters are given at the beginning of Sect. 5). Here η = 0.1 is shown as a black solid line, η = 0.5 as a black dotted line, and η = 0.6 as a black dashed line. The light gray line represents the fit of Eq. (33) for the η = 0.6 case (see text for details).
