Density distribution 15 kiloyear after sink formation and 2 kiloyear after zoom-in, obtained from zoom-in simulation (0.25 au resolution in the disc). The disc eccentric structure is apparent from both the ellipticity of the disc in the bottom (face-on) panel, as well as the scale height variation in the top (side-on) panel. The black dot marks the sink. The contours indicates the AMR level, with the disc sitting at the highest refinement level.
