The Milky Way retrograde halo contains debris from multiple accreted dwarf galaxies, shown by distinct metallicity distribution peaks that remain separate even when combined with orbital dynamics.
GALEX NUV excess shows an 8 sigma anti-correlation with [Fe/H] in 492 halo stars, enabling distinction of VMP stars but limited for EMP stars by chromospheric variability.
High-precision analysis of TYC 6044-714-1 favors s+r nucleosynthesis over i-process models, which require implausible conditions and mismatch Ba isotopes.
