Population III Star Absorption as a Method of Primordial Black Hole Search.
V. V. Malyshchits and V. V. Tikhomirov

A method of primordial black hole (PBH) search based on the Population III star (PIIIS) absorption is proposed. A slow PBH motion in the epoch of PIIIS formation makes efficient both PBH orbit contraction and further PBH deceleration leading to the population of dense PIIIS regions by PBHs. The following matter absorption allows PBHs with masses M>10²² g to completely absorb PIIISs for the time of their existence. The PIIISs absorption possibility opens up a new way of PBH search or establishing new constraints on the abundance of PBHs with masses from 10²² to 10³⁰ g.
Key words: primordial black hole, population III star, accretion
