Mixing stochasticity relinquishes evidence for magnetorotational hypernovae
Anmol Aggarwal, Ralph Schoenrich
A recent work claimed by fitting the observed elemental abundance pattern of a halo star with the total yields from single super-/hypernova events that only a magnetorotational hyp…
Tree-ring structure of Galactic bar resonance in N-body simulations
Rimpei Chiba, Michiko Fujii, Junichi Baba +2
We study the structure and evolution of the galactic bar's resonant phase-space in self-consistent N-body simulations of the Milky Way, with and without perturbations from the Sagi…
An unexplored enrichment stochasticity and its implications for stellar abundance patterns
Anmol Aggarwal, Ralph Schoenrich
Extremely low metallicity stars are intensely studied as they take observations the closest to the very first generations of stars in the universe. Widely assumed to be enriched by…
Radial Wave in the Galactic Disk: New Clues to Discriminate Different Perturbations
Chengye Cao, Zhao-Yu Li, Ralph Schönrich +1
Decoding the key dynamical processes that shape the Galactic disk structure is crucial for reconstructing the Milky Way's evolution history. The second Gaia data release unveils a…
