And if there are, we don’t know how to identify them from far away, do we?
Yes. Not from the star itself but rather by the interstellar dust (hydrogen atoms floating about, etc). We would detect emissions from interactions at the boundary between ‘mostly empty but with bits of matter’ and ‘mostly empty but with bits of antimatter’.
