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…
On the ridges, undulations & streams in Gaia DR2: Linking the topography of phase-space to the orbital structure of an N-body bar
F. Fragkoudi, D. Katz, W. Trick +7
We explore the origin of phase-space substructures revealed by the second Gaia data release in the disc of the Milky Way, such as the ridges in the - plane, the undulations…
