New VLT observations of He I* absorbers yield a primordial ³He/⁴He ratio of (1.15^{+0.24}_{-0.21})×10^{-4} consistent with standard Big Bang nucleosynthesis, plus an updated stellar yield scaling factor.
NGC 6791 has an age of 8.46 ± 0.66 Gyr, [Fe/H] = +0.280 ± 0.079, and other parameters that favor an inner-Galaxy origin followed by outward migration.
FIRE-2 simulations show that stellar radial redistribution scatter saturates at ~2 kpc for stars older than ~3 Gyr, with net orbital changes depending on age and current radius, broadly matching Milky Way observations.
