Vertical structure of an inner disk ring (left panels) at radius r = 13.38    ×    10⁸   cm and an outer disk ring (right) at r = 40.56    ×    10⁸   cm during quiescence at different effective temperatures for the accretion disk. Shown are the temperature T (bottom panel), the density ρ (middle), and the Rosseland optical depth τ_ross (top).
