Empirical derivation of the metallicity evolution with time and radius using TNG50 Milky Way/Andromeda analogues
B. Ratcliffe, S. Khoperskov, I. Minchev +3
Recent works have used a linear birth metallicity gradient to estimate the evolution of the [Fe/H] profile in the Galactic disk over time, and infer stellar birth radii (R$_\text{b…
