289 very metal-poor red giant stars were identified from the APOGEE survey data.
Among the identified stars, 16 candidates are from the Magellanic Clouds, enhancing stellar knowledge in those regions.
The study demonstrates how spectroscopic techniques can unveil stars with metallicity below detectable limits.
This research contributes to understanding early chemical evolution across different galactic environments.
