Or, the material out of which they were made could have arrived that way, being ex- of the supernova. There’s a link above to the “iron sun” topic and the underlying article (which isn’t linked at the topic, oddly) which suggests another scenario, which is that our Sun is itself the leftovers of the earlier star.
If Sol is the coalesced remnants of an earlier star, its lifetime would be limited.
It would reach an “antitypical” phase where it would enter death throes “early”.
Similar to certain blue straggler stars with “anomalous ages”.
