Specific radial torque density in units of (dΓ/dm)₀ for 2D and 3D embedded planet models using different mass ratio and disk temperature. The first three curves represent models with the same disk temperature H/r = 0.05. The red curve corresponds to our standard model, the blue curve has a reduced planet mass q = 3 × 10^-5, and the third (green curve) corresponds to a full 3D run. The next two curves (yellow and purple) refer to models with H/r = 0.037. The 2D runs used our approximate density distribution in evaluating the gravitational force. The 3D results were adapted from Kley et al. (2009) where the setup and numerics is described in more detail.
