Am I blind or does the paper not mention helium-2 at all? https://arxiv.org/abs/2212.04476 https://arxiv.org/abs/2212.04476 It talks extensively about "He II"

It talks extensively about "He II", the astrophysics notation for singly-ionized helium (a helium atom with one electron removed; He+). That isn't notation for a helium isotope. I can't see anything in the paper mentioning isotopes, nuclear reactions, or anything in that direction. (?)
- pfdietz 4y ago2He is not being observed, as it is not a bound nucleus. And this is a good thing! If 2He were bound, the pp fusion reaction would be much faster, our Sun would long since have burned out, and we would not be here.
