Accretion of Primordial Black Holes in Stellar Interiors
Matteo Cantiello, Ore Gottlieb, Cameron Norton +2
We study spherical accretion onto primordial black holes (PBHs) embedded in the core of a solar-type star. We compute the radiative efficiency self-consistently for the first time…

The Life and Death of Stars That Capture Primordial Black Holes
Ore Gottlieb, Matteo Cantiello, Cameron Norton +2
Primordial black holes (PBHs) in the asteroid mass window () remain viable dark matter candidates and can be captured by stars. We develop the first globa…
