Pressure vs. distance in disks at steady states with different water-vapor mass fraction (f) enhancement at the snow-line (located at 3 au here). Here, Ṁ = 10⁻⁹M_⊙ yr⁻¹ and p = 0.1 (top), p= 0.5 (middle), and p = 0.9 (bottom). The width of the water-vapor-rich region is arbitrarily set to 0.1 au (numerically and analytically derived in Hyodo et al. 2021a). For the same mass fraction of water vapor, the pressure bump amplitude increases for larger p.
