Lithium enhancements in several polluted white dwarfs are most consistent with Big Bang and Galactic nucleosynthesis rather than continental crust or spalled-ring exomoons, with one object defying all three explanations.
In NIHAO-UHD simulations, very metal-poor stars on planar retrograde orbits are almost all accreted during the first few billion years, while prograde planar stars sample later accretion as well.
Photometric analysis yields metallicity distributions for 3917 stars across 12 faint Milky Way satellites, showing average [Fe/H] ~ -2.3 dex, 170 EMP candidates, and no gradients in ultra-faint systems.
The paper assigns each of four G-type stars a globular-cluster birthplace using 13 Gyr backward orbits and encounter probabilities, but the statistical case is weak.
High-precision analysis of TYC 6044-714-1 favors s+r nucleosynthesis over i-process models, which require implausible conditions and mismatch Ba isotopes.
