Table 2

Approximate values of the scalar k3D∕1D for discrete values of αvisc.

αvisc k3D∕1D
0.01 1.5
0.001 2
0.0005 2.5
0.0001 5

Notes. This scalar tells us that for a specific value of αvisc, say 0.01, the planetary mass required to obtain a zero pressure gradient in our 1D simulations is 1.5 times lower than the mass obtained using the equation from Bitsch et al. (2018), which was obtained using 3D simulations.
