Azimuthally and temporally averaged gas radial density profiles, obtained using α = 0.01 and two different temperature profiles. As expected, the density profile resulting from the T ∝ R^-0.5 is steeper than the T ∝ R^-0.9 profile, and the density maximum in the first case is even farther away from the observed dust location (~ 200 AU) than in the latter case. Both density profiles are normalized to their maximum values.
