Zoom-in onto the inner disk regions at t = 0.2 Myr: left column –200 × 200 AU², middle column – 60 × 60 AU², and right column – 10 × 10 AU². Shown are the gas surface density in log g cm⁻² (top row), grown dust surface density in log g cm⁻² (second row), gas-to-grown dust mass ratio in log scale (third row), Stokes number in log scale (fourth row), and maximum radius of dust grains a_r in log cm. The contour lines in the third, fourth, and fifth rows delineate the spiral pattern in the gas surface density for convenience.
