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…
Optical spectroscopic signatures of the red giant evolutionary state
Ella Xi Wang, Melissa Ness, Thomas Nordlander +17
Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar pr…
