Dopita & Liebert (1989) infer the presence of a photo-evaporating highly inflated (0.6 R_Sol = 6 R_Jup) gas giant planet (assumed mass 10³⁰ g = 0.526 M_Jup) to explain the origin of EGB 6 planetary nebula. However neither planet ablation or exocomet evaporation are enough to account for the amount of ionized gas making up the nebula.
