Magnesium isotope ratios in Milky Way and dwarf galaxy stars
M. McKenzie, S. Monty, D. Yong +8
Under the assumption of hierarchical galaxy formation, dwarf galaxies are the closest existing analogues to the high-redshift protogalaxies that merged to form the Milky Way. These…
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 complex star cluster M 22 (NGC 6656) provides a unique opportunity for studying slow neutron-capture (s-process) nucleosynthesis at low metallicity due to its two stellar group…
The complex stellar system M 22: confirming abundance variations with high precision differential measurements
M. McKenzie, D. Yong, A. F. Marino +8
M 22 (NGC 6656) is a chemically complex globular cluster-like system reported to harbour heavy element abundance variations. However, the extent of these variations and the origin…
PySME v1.0: improved modelling of stellar spectra for survey-scale applications
Mingjie Jian, Nikolai Piskunov, Jeff Valenti +4
Stellar abundance analysis relies on flexible, high-performance spectral synthesis. To meet these needs, we present PySME v1.0, an updated Python implementation of Spectroscopy Mad…
3D NLTE Sodium abundances in late-type stars. Abundance corrections and synthetic spectra
G. Canocchi, E. X. Wang, A. M. Amarsi +2
Neutral sodium is an important tracer of the Galactic chemical evolution, a powerful diagnostic of different stellar populations, and the subject of detailed studies of exoplanet a…
