By analyzing high-resolution spectra for 11 red giant branch (RGB) stars, astronomers have conducted a chemical investigation of the globular cluster NGC 6723. Results of the study, presented in a paper published June 24 on arXiv.org, offer more insights on the chemical enrichment of NGC 6723 and could be important to better understand chemical composition of globular clusters in general.
