A., Xie, Y., Collaboration, The GALAH

The stars of the Milky Way carry the chemical history of our Galaxy in their atmospheres as they journey through its vast expanse. Like barcodes, we can extract the chemical fingerprints of stars from high-resolution spectroscopy. The fourth data rel

${S}^5$: The destruction of a bright dwarf galaxy as revealed by the chemistry of the Indus stellar stream

Autor: Hansen, T. T., Ji, A. P., Da Costa, G. S., Li, T. S., Casey, A. R., Pace, A. B., Cullinane, L. R., Erkal, D., Koposov, S. E., Kuehn, K., Lewis, G. F., Mackey, D., Shipp, N., Zucker, D. B., Bland-Hawthorn, J., Collaboration, the S5

The recently discovered Indus stellar stream exhibits a diverse chemical signature compared to what is found for most other streams due to the abundances of two outlier stars, Indus$\_$0 and Indus$\_$13. Indus$\_$13, exhibits an extreme enhancement i

Binary stellar systems form a large fraction of the Galaxy's stars. They are useful as laboratories for studying the physical processes taking place within stars, and must be correctly taken into account when observations of stars are used to study t
