Abstract

The space density of stars, and therefore, the possible number of planets are expected to be high in the central region of galaxies. While the galactic nuclei may be rather wild places due to the existence of the supermassive black holes and the surrounding accretion disks. As the first step to investigate the advanced civilizations in the galactic nuclei, the author examines the equilibrium temperature and related problems of possible planets in the vicinity of accretion disks.
