Two-body model for the spatial distribution of dust ejected from an atmosphereless body

We present a model for the configuration of noninteracting material that is ejected in continuous manner from an atmosphereless gravitating body given distribution sources. The applicable to on bound or unbound trajectories and steady nonsteady modes ejection. For jet inclined surface normal, we related distributions ejection direction, velocity, size phase-space number density at distance source body. Integrating over velocity space, obtained expression which inferred density, flux, optical depth material. As examples application code, calculate profiles dust Enceladus plume, pattern mass deposition rates around plume Europa, images following nonstationary emission volcano Io. make code Fortran-95 implementation freely available.
