# Superheavy objects composed of nuclear and dark matter

## TL;DR

This paper explores a model where dark matter composed of stable double-charged particles binds with helium nuclei, forming superheavy objects that could influence stellar evolution and create new types of nuclear matter.

## Contribution

It introduces the concept of $O$-nuclearites formed from $O$He atoms and discusses their potential self-bound states and impact on stars, a novel idea in dark matter research.

## Key findings

- $O$-nuclearites can be self-bound by nuclear and electromagnetic interactions.
- Accumulation of $O$He atoms in stars can affect stellar evolution.
- Potential formation of superheavy, gravitating dark matter objects.

## Abstract

We consider a model of $O$He 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 $O$He atoms in stars and their effect in stellar evolution.
