Infrared and Optical Detectability of Dyson Spheres at White Dwarf Stars
arXiv:2204.09627 · doi:10.1093/mnras/stac1113
Abstract
It has been hypothesized that advanced technological civilizations will construct giant space colonies and supporting infrastructures to orbit about their home stars. With data from recent satellites that operate at infrared and optical wavelengths (Spitzer, WISE, TESS, Kepler), in company with a few modest assumptions, it is now possible to begin to constrain observationally the frequency of such space-based civilizations in our Milky Way Galaxy.
