Orchestra is an ensemble of computer codes for calculating the formation and evolution of planetary systems.

  • Radial diffusion code: calculate the time evolution of a gaseous disk and small particles coupled to the disk.
  • Multiannulus coagulation code: derive the time evolution of the sizes and orbital parameters for a swarm of dust grains, planetesimals, and protoplanets
  • N-body code: follow the changing trajectories of individual planets and massless tracer particles
