 The gravitational potential entering in the source terms of the Navier-Stokes equations is the sum of multiple terms:
-1. The potential from the central massive body (primary of mass $`M_*`$):
+1. **The potential from the central massive body ** (primary of mass $`M_*`$):
 
    $`\Phi_*=-{{ G M_*} \over {r}}`$
 2. The potential form the planets of mass $m_p$.
