Magnesium isotope ratios in Milky Way and dwarf galaxy stars
M. McKenzie, S. Monty, D. Yong +8
The paper measures magnesium isotope ratios in stars from dwarf galaxies and the Milky Way, finding distinct patterns at fixed iron abundance but similar ratios at fixed magnesium…

The complex stellar system M 22: constraining the chemical enrichment from AGB stars using magnesium isotope ratios
M. McKenzie, D. Yong, A. I. Karakas +8
The paper measures magnesium isotope ratios in the globular‑cluster-like system M 22 and finds that low‑mass (1–3 M☉) AGB stars can explain its s‑process enrichment, while higher‑m…

The complex stellar system M 22: confirming abundance variations with high precision differential measurements
M. McKenzie, D. Yong, A. F. Marino +8
The authors perform high‑precision differential spectroscopy of six red‑giant stars in the globular‑cluster‑like system M 22, confirming internal abundance variations in many eleme…
