>Many different short-lived actinide elements, namely, actinium, protactinium, neptunium, plutonium, americium, curium, berkelium, californium, and einsteinium have been reported in the absorption spectrum.[25][26] Radioactive elements have also been reported to include technetium and promethium.[25][27] While the longest-lived known isotopes of technetium have half-lives in the millions of years, the longest-lived known promethium isotope has a half-life of only 17.7 years. The presence of these elements in the stellar atmosphere would imply some process constantly replenishing it.
Where does this star get elements that we have to create in a lab, and in such abundance that we can detect them from 356 light-years away? And why not take a closer look at this with JWST?

>Przybylski's star has occasionally attracted attention as a SETI candidate[33] insofar as it aligns with speculation that a technological species may salt the photosphere of its star with unusual elements, either to signal its presence to other civilizations[34][35] or to dispose of nuclear waste.[36]
