Modelling the chemical evolution of the Milky Way [PDF]
The Astronomy and Astrophysics Review, 2021 AbstractIn this review, I will discuss the comparison between model results and observational data for the Milky Way, the predictive power of such models as well as their limits. Such a comparison, known as Galactic archaeology, allows us to impose constraints on stellar nucleosynthesis and timescales of formation of the various Galactic components ...

Chemodynamical Evolution of the Milky Way [PDF]
Symposium - International Astronomical Union, 2003 We simulate the chemodynamical evolution of the Milky Way using our GRAPE-SPH code, and reproduce the age-metallicity relation, the [O/Fe]-[Fe/H] relation, and the metallicity distribution.

Dynamical evolution of a bulge in an N-body model of the Milky Way [PDF]
, 2011 The detailed dynamical structure of the bulge in the Milky Way is currently under debate. Although kinematics of the bulge stars can be well reproduced by a boxy-bulge, the possible existence of a small embedded classical bulge can not be ruled out.

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 ...

The Gaia-ESO Survey: the selection function of the Milky Way field stars [PDF]
, 2016 The Gaia-ESO Survey was designed to target all major Galactic components (i.e., bulge, thin and thick discs, halo and clusters), with the goal of constraining the chemical and dynamical evolution of the Milky Way.

The influence of nova nucleosynthesis on the chemical evolution of the Galaxy [PDF]
, 2000 We adopt up-to-date yields of 7Li, 13C, 15N from classical novae and use a well tested model for the chemical evolution of the Milky Way in order to predict the temporal evolution of these elemental species in the solar neighborhood.

Chemical evolution of the Milky Way: the origin of phosphorus [PDF]
Astronomy & Astrophysics, 2012 Context. Recently, for the first time the abundance of P has been measured in disk stars. This provides the opportunity of comparing the observed abundances with predictions from theoretical models. Aims. We aim at predicting the chemical evolution of P in the Milky Way and compare our results with the observed P abundances in disk stars in order to ...

A synthetic view on structure and evolution of the Milky Way [PDF]
Astronomy & Astrophysics, 2003 Since the Hipparcos mission and recent large scale surveys in the optical and the near-infrared, new constraints have been obtained on the structure and evolution history of the Milky Way. The population synthesis approach is a useful tool to interpret such data sets and to test scenarios of evolution of the Galaxy.
