Just an hour ago, I learned about Przybylski's Star. [0]
> Przybylski's observations indicated unusually low amounts of iron and nickel in the star's spectrum, but higher amounts of unusual elements such as strontium, holmium, niobium, scandium, yttrium, caesium, neodymium, praseodymium, thorium, ytterbium, and uranium.
While the explanation is likely some unknown natural process, salting a star with an impossible chemical composition might also be a way for a technological species to create a monument, correct? This seems like it would involve moving less mass around than a Dyson Sphere/Swarm, although it would need a constant feed, if I understand the situation correctly.
Astonishingly, there appears to be no contemporary analysis of this star.
