The GALAH survey: Tracing the Milky Way's formation and evolution through RR Lyrae stars
Valentina D'Orazi, Nicholas Storm, Andrew R. Casey +39
Stellar mergers and accretion events have been crucial in shaping the evolution of the Milky Way (MW). These events have been dynamically identified and chemically characterised us…
High resolution spectroscopic follow-up of the most metal-poor candidates from SkyMapper DR1.1
D. Yong, G. S. Da Costa, M. S. Bessell +13
We present chemical abundances for 21 elements (from Li to Eu) in 150 metal-poor Galactic stars spanning 4.1 [Fe/H] 2.1. The targets were selected from the SkyMapper…
: The destruction of a bright dwarf galaxy as revealed by the chemistry of the Indus stellar stream
T. T. Hansen, A. P. Ji, G. S. Da Costa +13
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, Indu…
The GALAH Survey: No chemical evidence of an extragalactic origin for the Nyx stream
Daniel B. Zucker, Jeffrey D. Simpson, Sarah L. Martell +20
The results from the ESA Gaia astrometric mission and deep photometric surveys have revolutionized our knowledge of the Milky Way. There are many ongoing efforts to search these da…
Targeting Bright Metal-poor Stars in the Disk and Halo Systems of the Galaxy
Guilherme Limberg, Rafael M. Santucci, Silvia Rossi +7
We present the results of spectroscopic follow-up for 1897 low-metallicity star candidates, selected from the Best & Brightest (B&B) Survey, carried out with the GMOS-N/S (Gemini N…
Exploring the Galaxy's halo and very metal-weak thick disk with SkyMapper and Gaia DR2
G. Cordoni, G. S. Da Costa, D. Yong +16
In this work we combine spectroscopic information from the \textit{SkyMapper survey for Extremely Metal-Poor stars} and astrometry from Gaia DR2 to investigate the kinematics of a…
