Radial distribution of simple (CH4 and CS) and carbon-chain molecules at t = 1.7×105, 2.2×105, 3.0×105, and 5.0×105 yr in the fiducial model. The light gray shadow covers the hot corino regions within the dust temperature >100 K. The dark-gray shaded areas represent the WCCC regions within the dust temperature from 20 to 35 K. The different molecules are distinguished by line colors and marks. The solid lines show the gaseous abundances, while the dashed lines depict the icy abundances.
