The chemical evolution of barium and europium in the Milky Way [PDF]
Astronomy & Astrophysics, 2006 We compute the evolution of the abundances of barium and europium in the Milky Way and we compare our results with the observed abundances from the recent UVES Large Program "First Stars". We use a chemical evolution model which already reproduces the majority of observational constraints.

Forward Modelling the Secular Evolution of the Milky Way Disk [PDF]
, 2021 We know precisely the position of the Sun in our Galaxy. Yet, like for most stars, we cannot tell where it was born. Stars undergo dynamical memory loss: their orbits evolve, because the Milky Way, like many galaxies, has non-axisymmetric structures ...

The Astrophysical Journal, 2023 We continue our series of papers on phase-space distributions of stars in the Milky Way based on photometrically derived metallicities and Gaia astrometry, with a focus on the halo−disk interface in the local volume.

The chemical evolution of the Milky Way [PDF]
Proceedings of Frontier Research in Astrophysics – II — PoS(FRAPWS2016), 2017 We will discuss some highlights concerning the chemical evolution of our Galaxy, the Milky Way. First we will describe the main ingredients necessary to build a model for the chemical evolution of the Milky Way. Then we will illustrate some Milky Way models which includes detailed stellar nucleosynthesis and compute the evolution of a large number of ...

Overview of the DESI Milky Way Survey
The Astrophysical Journal, 2023 We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4 m telescope at the Kitt Peak National Observatory.

The formation and early evolution of the Milky Way [PDF]
Symposium - International Astronomical Union, 1985 In broad outline, the traditional picture for the formation of the Milky Way can be summarized as follows. The proto-galaxy consisted of a slowly rotating cloud of metal-free gas that cooled by bremsstrahlung and recombination radiation. As the internal pressure of the gas decreased, it collapsed in stages with smaller dimensions, faster rotation ...

The Tilt of the Velocity Ellipsoid of Different Galactic Disk Populations
The Astrophysical Journal, 2023 The tilt of the velocity ellipsoid is a helpful tracer of the gravitational potential of the Milky Way. In this paper, we use nearly 140,000 red clump (RC) stars selected from LAMOST and Gaia to make a detailed analysis of the tilt of the velocity ...

Formation and Evolution of the Milky Way [PDF]
Symposium - International Astronomical Union, 1997 To paint with broad brush strokes, the spectrum of Galactic formation models has as extrema what may be termed the “fast and smooth” and the “slow and lumpy” scenarios. Appropriate or not, to ascribe as champions of these views the works of, respectively, Eggen et al.
