Abstract : We present an efficient multi-body code devoted to self-gravitating polytropic stars and rings in mutual gravitational interaction. The code implements the Self-Consistent Field method which captures solutions in an iterative manner. It works for any positive polytropic index, rotation law and configuration (axis ratios and relative separations). The number of bodies is free. We have investigated a wide range of equilibria involving 2 up to 8 bodies. A model for the disk around HL Tau is currently under progress.
