Evolution of the vertical positions (upper left panel), radial positions (upper center panel), temperatures (upper right panel), local UV fluxes (lower left), and local molecular number density in the gas phase (lower center) for monomers in home aggregates with different fragmentation velocity υ_frag, released from r = 10 AU and z/r = 0. The black dashed line in the lower left panel indicates a UV radiation field strength of 1 F_Draine. Linestyles in the lower center panel indicate number densities of different gas phase species.
