Temperature in the meridional plane for our reference model MREF, a young solar-type star with a radially-uniform mass accretion rate of 3.6 × 10⁻⁹ M_⊙ yr⁻¹, a dust-to-gas mass ratio for small grains of 0.001 and stress-to-pressure ratios of α_MRI = 0.01 and α_DZ = 0.001. The green solid line shows optical depth τ = 2∕3 for the starlight irradiation. The yellow dashed line shows the silicate sublimation front. The white solid line shows the water sublimation front. The white circle shows the location of the pebble trap, where large grains would concentrate.
