The SkyMapper search for extremely metal-poor stars in the Large Magellanic Cloud
W. S. Oh, T. Nordlander, G. S. Da Costa +2
We present results of a search for extremely metal-poor (EMP) stars in the Large Magellanic Cloud, which can provide crucial information about the properties of the first stars as…
The Magellanic Edges Survey IV. Complex tidal debris in the SMC outskirts
L. R. Cullinane, A. D. Mackey, G. S. Da Costa +2
We use data from the Magellanic Edges Survey (MagES) in combination with Gaia EDR3 to study the extreme southern outskirts of the Small Magellanic Cloud (SMC), focussing on a field…
Spectroscopic follow-up of statistically selected extremely metal-poor star candidates from GALAH DR3
G. S. Da Costa, M. S. Bessell, Thomas Nordlander +5
The advent of large-scale stellar spectroscopic surveys naturally leads to the implementation of machine learning techniques to isolate, for example, small sub-samples of potential…
A high-resolution spectroscopic search for multiple populations in the 2 Gyr old cluster NGC 1846
Wei Shen Oh, Thomas Nordlander, Gary Da Costa +1
We present detailed C, O, Na, Mg, Si, Ca, Ti, V, Fe, Zr, Ba, and Eu abundance measurements for 20 red giant branch (RGB) stars in the LMC star cluster NGC 1846 ([Fe/H] = -0.59). Th…
The Magellanic Edges Survey III. Kinematics of the disturbed LMC outskirts
L. R. Cullinane, A. D. Mackey, G. S. Da Costa +3
We explore the structural and kinematic properties of the outskirts of the Large Magellanic Cloud (LMC) using data from the Magellanic Edges Survey (MagES) and Gaia EDR3. Even at l…
Evidence of globular cluster abundance anomalies in the SMC intermediate-age cluster Kron 3
C. Salgado, G. S. Da Costa, D. Yong +5
Using spectra obtained with the VLT/FORS2 and Gemini-S/GMOS instruments we have investigated carbon, nitrogen and sodium abundances in a sample of red giants in the Small Magellani…
