(Phys.org)—An international team of astronomers has performed detailed measurements of the chemical composition of 158 red giant stars in the nearby Sagittarius dwarf galaxy. The study, presented in a paper published July 11 on arXiv.org, is so far the largest and most chemically extensive high-resolution survey of this galaxy.
