Stellar Engines

A stellar engine, such as the Shkadov thruster named after Soviet aeronautics scientist Leonid Mikhailovich Shkadov, is a megastructure built around a star for the purpose of moving that star and any orbiting planets. Several variants of the Shkadov thruster have been hypothesized, including the Badescu-Cathcart engine, the Caplan thruster and the Star Tug.

Detectability

  • The unusual movement of an artificially propelled star could be detectable when compared with the movement of adjacent stars.
