Density as a function of radius in protoplanetary atmospheres around cores of 0.1 M and 1 M and for nebula gas densities varying from 5 × 10-10 g/cm3 to 5 × 10-25 g/cm3 with steps of one magnitude. The inner and outer boundaries are defined by the radius of the solid core and by the Hill radius, respectively.
