Superheavy objects composed of nuclear and dark matter

We consider a model of OHe atomic dark matter formed by Coulomb binding of the hypothetical stable double-charged massive O ^{– –} particles with nuclei of primordial helium. Such a dark matter can be captured by ordinary matter forming superheavy nuclei. We propose a possibility of self-bound by nuclear and electromagnetic interaction O-nuclearites as well as more massive gravitating ones and discuss effect of accumulation of OHe atoms in stars and their effect in stellar evolution.
