The aging and gradual brightening of the Sun will challenge Earth's habitability in the next few billion years. If life exists elsewhere in the Universe, the aging of their host star will similarly pose an existential threat. One solution to this threat, which we dub a Lazarus star, is for an advanced civilization to remove (or "star-lift") mass from their host star at a rate which offsets the increase in luminosity, keeping the flux on the habitable planet(s) constant and extending the lifetime of their star.
