Observational Constraints of Radial Migration in the Galactic Disc Driven by the Slowing Bar
HanYuan Zhang, Vasily Belokurov, N. Wyn Evans +7
Radial migration is an important dynamical effect that has reshaped the Galactic disc, but its origin has yet to be elucidated. In this work, we present evidence that resonant drag…

Deciphering the Milky Way disc formation time encrypted in the bar chrono-kinematics
Hanyuan Zhang, Vasily Belokurov, N. Wyn Evans +3
We present a novel method to constrain the formation time of the Milky Way disc using the chrono-kinematic signatures of the inner Galaxy. We construct an O-rich Mira variable samp…
