Description

We consider a model of $OHe$ atomic dark matter formed by Coulomb binding of the stable double charged massive $O^{--}$ particles with nuclei of primordial helium. Such dark matter can be captured by ordinary matter forming superheavy nuclei. We discuss $O$-nuclearites formed by multiple capture of $O^{--}$ particles by heavy nuclei and effect of accumulation of $OHe$ atoms in stellar evolution.
