Bimodality of [α/Fe]-[Fe/H] distributions is a natural outcome of dissipative collapse and disc growth in Milky Way-type galaxies
Sergey Khoperskov, Misha Haywood, Owain Snaith +5
We present a set of self-consistent chemo-dynamical simulations of MW-type galaxies formation to study the origin of the bimodality of -elements in stellar populations. We explo…
Double X/Peanut Structures in Barred Galaxies -- Insights from an --body Simulation
Bogdan C. Ciambur, Francesca Fragkoudi, Sergey Khoperskov +2
Boxy, peanut- or X-shaped "bulges" are observed in a large fraction of barred galaxies viewed in, or close to, edge-on projection, as well as in the Milky Way. They are the product…
Escapees from the bar resonances. On the presence of low-eccentricity, metal-rich stars at the Solar vicinity
S. Khoperskov, P. Di Matteo, M. Haywood +2
Understanding radial migration is a crucial point to build relevant chemical and dynamical evolution models of the Milky Way disk. In this paper, we analyze a high-resolution N-bod…
Hic sunt dracones: Cartography of the Milky Way spiral arms and bar resonances with Gaia Data Release 2
S. Khoperskov, O. Gerhard, P. Di Matteo +5
In this paper we introduce a new method for analysing Milky Way phase-space which allows us to reveal the imprint left by the Milky Way bar and spiral arms on the stars with full p…
Revisiting long-standing puzzles of the Milky Way: the Sun and its vicinity as typical outer disk chemical evolution
M. Haywood, O. N. Snaith, M. D. Lehnert +2
We present a scenario of the chemical enrichment of the solar neighborhood that solves the G-dwarf problem by taking into account constraints on a larger scale. We argue that the M…
The disc origin of the Milky Way bulge: On the necessity of the thick disc
P. Di Matteo, F. Fragkoudi, S. Khoperskov +4
In the MW bulge, metal-rich stars form a strong bar and are more peanut-shaped than metal-poor stars. It has been recently claimed that this behavior is driven by the initial in-pl…
