Astronomers find 'gold standard' star in Milky Way
In our sun's neighborhood of the Milky Way Galaxy is a relatively bright star, and in it, astronomers have been able to identify the widest range of elements in a star beyond our solar system yet.
The Astrophysical Journal Supplement publishes significant papers containing extensive data or calculations, or of very specialized interest. The Supplement contains many of the most frequently cited papers in the astronomical literature.
