Radial profile of the density in the (x–y)-plane at t≈2.5 kyr in the R–SINKt0 (purple line), R–NOSINKt0 (purple, dotted line), and PLUTO (blue line). At this stage, initial axisymmetry is maintained. Towards the center, the density settles in a plateau, forming a disk structure with an additional density bump in R–SINKt0 and PLUTO, while it continuously decreases in R–NOSINKt0 and forms a ring around 30 AU.
