The energy injection through Hawking evaporation has been used to put strong constraints on primordial black holes as a dark matter candidate at masses below $10^{17}\,\rm{g}$. However, Hawking's semiclassical approximation breaks down latest after half-decay. Beyond this point, the could be significantly suppressed, was shown in recent work. In study, we review existing cosmological and astrophysical bounds holes, taking effect into account. We show that disappear completely for reasonable...

Abstract If primordial black holes (PBHs) of asteroidal mass make up the entire dark matter, they could be detectable through their gravitational influence in solar system. In this work, we study perturbations that PBHs induce on orbits planets. Detailed numerical simulations system, embedded a halo PBHs, are performed. We find effect is dominated by closest encounter. Using Earth–Mars distance as an observational probe, show smaller than current measurement uncertainties and thus not...
If primordial black holes (PBHs) of asteroidal mass make up the entire dark matter they could be detectable through their gravitational influence in solar system. In this work, we study perturbations that PBHs induce on orbits planets. Detailed numerical simulations system, embedded a halo PBHs, are performed. Using Earth-Mars distance as an observational probe, show below current detection limits and thus not directly constrained by system ephemerides. We estimate improvement measurement...
