Stellar engines are a class of hypothetical megastructures which use the resources of a star to generate available work (also called exergy). For instance, they can use the energy of the star to produce mechanical, electrical or chemical work or they can use the impulse of the light emitted by the star to produce thrust, able to control the motion of a star system.[1] The concept has been introduced by Bădescu and Cathcart.[2] The variants which produce thrust may accelerate a star and anything orbiting it in a given direction.[3][4] The creation of such a system would make its builders a type-II civilization on the Kardashev scale.

It consists of a partial Dyson swarm composed of 5 Dyson rings of solar collectors (the class-B component), and a large statite Shkadov thruster (the class-A component). Perspective is from below the system's ecliptic at a distance of ~2.8 AU . The system's direction of acceleration is on a vector from the center of the star through the center of the Shkadov thruster, which is hovering over the star's
