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 ...

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.

Chemical evolution in the Milky Way Disk

AIP Conference Proceedings, 2006
Classical models of galactic evolution predict a smooth rise in heavy‐element abundance (metallicity) with time. We test this prediction with a new, large and unbiased sample of long‐lived stars in the solar neighbourhood and find that several of the key tests fail to support the classical predictions.

Chemo-Spectral Evolution of the Milky way and of Spiral Disks

Astrophysics and Space Science, 1999
Our model and its application to the Milky Way are discussed in detail in Boissier & Prantzos (1998). The stellar yields of Woosley & Weaver (1995) are used to compute the chemical evolution, while the spectral one is coherently followed with the stellar evolution tracks of the Geneva group (Schaller et al. (1992), Charbonnel et al.
