The Three-phase Evolution of the Milky Way

The Astrophysical Journal
We illustrate the formation and evolution of the Milky Way over cosmic time, utilizing a sample of 10 million red giant stars with full chemodynamical information, including metallicities and α -abundances from low-resolution Gaia XP spectra.

The Chemical Evolution of the Milky Way [PDF]

, 1999
The field of chemical evolution modeling of the Galaxy is experiencing in the last years a phase of high activity and important achievements. There are, however, several open questions which still need to be answered. In this review I summarize what have

Chemical Evolution of Fluorine in the Milky Way [PDF]

Monthly Notices of the Royal Astronomical Society, 2022
ABSTRACT Fluorine has many different potential sites and channels of production, making narrowing down a dominant site of fluorine production particularly challenging. In this work, we investigate which sources are the dominant contributors to the galactic fluorine by comparing chemical evolution models to observations of fluorine ...

The chemical evolution of Barium and Europium in the Milky Way [PDF]

Astronomy & Astrophysics, 2005
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".

Formation and Evolution of the Milky Way [PDF]

Symposium - International Astronomical Union, 1998
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.

The evolution of carbon and oxygen in the bulge and disk of the Milky Way [PDF]

Astronomy & Astrophysics, 2009
The evolution of C and O abundances in the Milky Way can impose strong constraints on stellar nucleosynthesis and help understanding the formation and evolution of our Galaxy. The aim is to review the measured C and O abundances in the disk and bulge of the Galaxy and compare them with model predictions.

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.
