Decoding the Chemical Puzzle of the Sagittarius Dwarf Galaxy

Researchers analyzed 37 stars in the Sagittarius Dwarf Galaxy to study its chemical evolution. They found significant enrichment of heavy elements through the r-process, likely from neutron star mergers. Stars in the galaxy's core and tidal streams showed similar chemical patterns, indicating a shared history. The study highlights how dwarf galaxies contribute to the universe's chemical complexity.
