How the Milky Way built its Disk

The Milky Way is an unusually typical galaxy. Yet, star-by-star, we can
observe orbits, ages and the detailed element composition of the stellar birth material.
This makes the Milky Way a unique model organism
for studying the mechanisms of galaxy formation. Even before the
advent of Gaia data, a vast set of spectroscopic stellar surveys has
shown us that the Milky Way's disk shows looks very
different -- and must have evolved quite different - from what
has been thought a decade ago.
