Chemical abundance distribution as a function of [Fe/H], Stars in blue are those studied in this work. The chemical abundances are those obtained using the spectroscopic log ɡ. The teal dots (prograde stars from Mackereth et al. 2021) and black contours (GALAH DR3 retrograde metal-poor stars) are the same control sample stars adopted in Fig. 5. The chemical elements are ordered according to their main nucleosynthetic channel: α-capture, iron peak, neutron-capture, and odd-Z. Within each nucleosynthetic channel, the chemical elements are organized according to atomic number.
