This artist’s concept depicts the chemical composition of the newly discovered stellar population traveling around the Milky Way on large eccentric orbits (white dashed line) and the typical APOGEE combined spectra of the atypical stars in a narrow spectral window, covering the regions (grey shadow) around of the magnesium features.
