The function $f=(f_r,f_\varphi,f_\theta)$ is the divergence of the
|
|
|
stress tensor (see for example Tassoul 1978).

The potential $\Phi$ acting on the disc consists of the contribution of
|
|
|
the star $\Phi_*=-GM_{*}/r$ and planets $\Phi_p$, plus indirect terms that arise from the primary acceleration due to the planets’ and disc’s gravity. |
