Evolution of action-space coherence in a Milky Way-like simulation
Arunima Arunima, Mark R. Krumholz, Michael J. Ireland +2
Efforts to dynamically trace stars back to the now-dissolved clusters in which they formed rely implicitly on the assumption that stellar orbital actions are conserved. While this…

Fundamental limits to orbit reconstruction due to non-conservation of stellar actions in a Milky Way-like simulation
Arunima Arunima, Mark Krumholz, Michael Ireland +2
The conservation of stellar actions is a fundamental assumption in orbit reconstruction studies in the Milky Way. However, the disc is highly dynamic, with time-dependent, non-axis…
