Abstract
The exact mathematical expression for an arbitrary nth-order stellar hydrodynamic equation is explicitly obtained depending on the central moments of the velocity distribution. In such a form the equations are physically meaningful, since they can be compared with the ordinary hy- drodynamic equations of compressible, viscous fluids. The equations are deduced without any particular assumptions about symmetries, steadi- ness, or particular kinematic behaviours, so that they can be used in their c...
