trailAccretion by micro black holes inside dense stars is limited by the Eddington luminosity.
Eddington-limited accretion by metastable micro black holes would evade existing astrophysical observations.
A black hole accreting hazardously fast on Earth would accrete faster inside white dwarfs or neutron stars.
A rapidly accreting captured black hole would destroy its host star on timescales shorter than observed stellar ages.

Photon trapping and Bondi accretion· against
Radiation from a micro black hole accreting inside dense stellar matter is trapped and advected inward with the accretion flow
For micro black holes accreting in white-dwarf or neutron-star matter, the photon trapping radius far exceeds the Bondi radius
Accretion flow onto a black hole embedded inside a star is quasi-spherical rather than disk-like
Black holes inside neutron stars accrete at the Bondi rate without radiative feedback halting the accretion
Micro black holes captured inside neutron stars or white dwarfs accrete at approximately the Bondi rate
General-relativistic simulations of black holes accreting inside neutron stars find Bondi-type accretion rates proportional to the horizon area
Stellar rotation imparts enough angular momentum to slow a captured black hole's accretion well below the Bondi rate
