Astronomers discover two new giant lithium-rich stars in an old open cluster

(Phys.org)—An international team of astronomers, led by Rodolfo Smiljanic of the Nicolaus Copernicus Astronomical Center in Toruń, Poland, has detected two new giant lithium-abundant stars in an old open cluster named Trumpler 20. The discovery could yield new important information regarding the phenomenon of omnipresence of lithium-rich stars in different environments throughout the universe. The results were published online on May 6 in the arXiv journal.
