The original idea for these is reflected in the development of Matrioshka Brains; another conception of them posits statites which support the weight of photovoltaic cells.

They would be characteristic of Type II Kardashev populations, and were introduced by their namesake in a 1959 article entitled "Search for Artificial Stellar Sources of Infra-Red Radiation." Theoretically, they have radii equal to the orbital distance of the home planet of the civilization in question, and are able to harness all energy from their parent stars. FTP, name these hypothetical megastructures which enclose stars and allow for extraterrestrial life, ►certain spheres named for a physicist Freeman.
