The disk(s) of the Milky Way

AIP Conference Proceedings, 2013
We present a review of formation of the Milky Way's disk(s). We discuss the most recent disk formation and evolution scenarios that can be probed by the orbital eccentricities of stellar populations. These scenarios are included in two different frames, namely violent origin and secular evolution.

The chemical evolution of the Milky Way disk [PDF]

Nuclear Physics A, 1997
Abstract The chemical evolution of the disk of our Galaxy is studied with numerical models assuming infall and a radially varying star formation rate (SFR). We propose a model with a minimal set of physically plausible assumptions which satisfies the main observational constraints of the disk, including those of the solar neighborhood.

EVOLUTION OF THE MILKY WAY DISK

2006
The Solar neighbourhood is where the physical basis for models of the evolu- tion of spiral galaxy disks can be tested most stringently. A new survey has provided full space motions, metallicities, ages, and duplicity information for over 14,000 nearby F and G dwarfs.

The Evolution of the Milky Way Disk

2000
The Milky Way is a heterogeneous system, with at least three components (halo, bulge, disk) having very different chemical, photometric and kinematical properties. A reliable model for the evolution of the Milky Way accounting for those properties does not exist at present.

The Milky Way disk non‐axisymmetries and galactoseismology

Astronomische Nachrichten, 2016
AbstractCurrent Galactic dynamical models still most often rely on the assumptions of a smooth time‐independent and axisymmetric gravitational potential. On the other hand, ab initio simulations in a cosmological context are not very flexible to precisely produce a model of our own Galaxy, or to disentangle the internal and the external/environmental ...

Quasar Candidates behind the Milky Way Disk and M31

Research Notes of the AAS, 2019
Quasars behind the Milky Way, M31 and other nearby galaxies are useful for absorption line studies. Here we report spectroscopic follow-up of four quasar candidates behind the Galactic plane and two behind the Andromeda galaxy.
