Star Lifting

Removing matter from a star using the power of its own luminosity

Starlifting, Star Lifting

Removing material from a star for industrial use or for stellar husbandry. The energy required for this process comes from the star itself, either directly from its luminosity or from fusion or matter conversion of the lifted material.

Magnetic arrays around Dschubba accelerate this already fast-spinning star, causing mass to be ejected from the equator
Methods include increasing the star's rotation until material begins to drift off the equator, or by magnetically squeezing the star until matter is expelled from the poles.

Most recently the Sirian Hierarchy have begun an ambitious project to starlift Sirius A; pictured above are the first of billions of devices placed in orbit to commence the process of stellar engineering which will extend the lifetime of the star for billions, perhaps trillions of years. The ring of magnetic accelerators has spun Sirius A into a flattened disk shape. Tuned lasers, shining inwards from the sphere of solar collectors, give the plasma the extra boost it needs to leap off into space where it cools and is collected. As the process continues through millions of years the star will shrink, yielding up nearly two solar masses of hydrogen in the process. Then it will settle into a comfortable red dwarf stage, and the collectors will be linked together into an unbroken sphere supported by light pressure. Before, its fuel would have been spent in a scant billion years, wasted into the void of space in the blink of an eye. After it is lifted, the fate of the Dog Star will not be death, but life. It will burn for a trillion years, as will the ten new stars built from its liberated substance, and its light will support the existance of uncountable lives. Farming the stars: a necessary process to sustain any advanced civilization.

    A solar output enhancement array. It consists of solar sails placed in balanced positions above the northern and southern hemispheres of a star. The array reflects the output of the star back onto its surface, thereby heating the outer layers and causing the star's spectrum to shift upward. The result for planets and habitats orbiting in the plane of the ecliptic is that the star appears to change from its original classification (typically M or K) to a more Sol-like spectrum (G-class).

  • Stellar Husbandry - Text by Dave Criswell, in Anders Sandberg's Transhuman Terminology
    A type of stellar engineering which involves controlling the evolution and properties of stars, especially to stabilize them, prolong their lifetimes, manipulate the stellar wind, lift off useful material or create new stars. Typical methods include star lifting or mixing the stellar core with envelope material to make hydrogen burning last longer.
