Primordial black hole-star binaries via dynamical friction
Nicolas Esser
We study a new channel for binary system formation involving stars and stellar-mass primordial black holes (PBHs) embedded in dark matter (DM) minihalos. In this scenario, binaries…

Constraints on asteroid-mass primordial black holes in dwarf galaxies using Hubble Space Telescope photometry
Nicolas Esser, Carrie Filion, Sven De Rijcke +4
Primordial black holes (PBHs) in the asteroid-mass range remain a viable and until now unconstrained dark matter (DM) candidate. If such PBHs exist, they could be captured by stars…
