Density snapshots for the star–disk collision with different resolutions and SMR levels. Each column represents a different configuration: the first four columns correspond to a resolution of 1024 × 1600 with SMR levels 0, 1, 2, and 3, respectively, while the fifth column shows results at a uniform resolution of 4096 × 6400. Note that the effective highest resolution of the third column (1024 × 1600 with SMR level 2) around the star is equivalent to the resolution of the fifth column. Rows represent the simulation time at frames −43.6 s, 43.6 s, 174.5 s, and 327.2 s, from top to bottom. The gray horizontal lines represent the disk’s midplane, and the green lines represent 4H_d from the midplane.
