Accretion onto a Limit Remnant: Bondi Capture and Eddington Output of a Heavy Relic
Year: 2026
Type: article
Abstract: The Bondi radius is 1.156e-07 metres, about a tenth of a micrometre, and the capture rate is 7.021e-31 kilograms per second. The Eddington ceiling of 5.474e+11 watts is formally large but irrelevant, because the luminosity at ten percent efficiency on the Bondi supply is only 6.310e-15 watts, some twenty-six orders below the ceiling; the growth time is 3.908e+33 years, vastly exceeding the cosmic age. Accretion therefore neither grows remnants nor lights them up: the objects are inert for the whole history of the universe at these rates. The result closes an escape route that remnant scenarios sometimes rely on. Computed from stated assumptions, not measured.
