> My very uneducated guess was that two planet-like objects smashed, and there is some cloud around the star which gave those weird spectrographs?
Another guess: it got close to a neutron star merger, and was showered with high atomic number debris. Heavy elements can be produced in mergers of such stars.
Something which might align with this guess is that this type of star apparently has an extremely strong magnetic field which could trap, and excite those particles?
However, assuming that it's not misidentification, would it be fair to say that new physics would have to be discovered to explain things like Americium and Einsteinium?
> One such theory is that the star contains some long-lived nuclides from the island of stability (such as 298Fl or 304Ubn) and that the observed short-lived actinides are the daughters of these progenitors, occurring in secular equilibrium with their parents.
