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…
Ripples of Stellar Enrichment (RoSE) -- simulating element production and mixing in the Milky Way star-by-star
Chuhan Zhang, Mark R. Krumholz, Melissa K. Ness +3
We present the Ripples of Stellar Enrichment (RoSE) simulations, which follow a Milky Way-like isolated disc galaxy with star-by-star feedback and nucleosynthesis from all signific…
Metallicity fluctuation statistics in the interstellar medium and young stars -- II. Elemental cross-correlations and the structure of chemical abundance space
Mark R. Krumholz, Yuan-Sen Ting, Zefeng Li +3
Observations of Milky Way stars by multiplexed spectroscopic instruments and of gas in nearby galaxies using integral field units have made it possible to measure the abundances of…
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…
Understanding the Mechanisms Behind the Distribution of Galactic Metals
Chuhan Zhang, Zefeng Li, Zipeng Hu +1
The evolution and distribution of metals within galaxies are critical for understanding galactic evolution and star formation processes, but the mechanisms responsible for shaping…
