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.

The Three-phase Evolution of the Milky Way
The Astrophysical JournalWe 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.

Modelling the chemical evolution of the Milky Way [PDF]
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 ...

A synthetic view on structure and evolution of the Milky Way [PDF]
Astronomy and 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.

Chemodynamical evolution of the Milky Way disk [PDF]
Astronomy and Astrophysics, 2013 In the first paper of this series, we present a new approach for studying the chemo-dynamical evolution in disk galaxies, which consists of fusing disk chemical evolution models with compatible numerical simulations of galactic disks. This method avoids known star formation and chemical enrichment problems encountered in simulations.

Structure and Evolution of the Inner Milky Way Galaxy [PDF]
Astrophysics and Space Science, 2001 The DENIS/ISOGAL near/mid-IR survey of the Milky Way for the first time probes stellar populations in the innermost obscured regions of our galaxy. Ages, metallicities and extinction-corrected luminosities are derived for these stars individually. An old metal-rich population dominates in the inner galactic Bulge, but there are also indications for the

The Astrophysical Journal, 2023 We have for the first time identified the early stellar disk in the Milky Way by using a combination of elemental abundances and kinematics. Using data from APOGEE DR17 and Gaia we select stars in the Mg–Mn–Al–Fe plane with elemental abundances ...

Chemical evolution of fluorine in the Milky Way
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 ...

Chemodynamical Analysis of Metal-rich High-eccentricity Stars in the Milky Way's Disk
The Astrophysical Journal, 2023 We present a chemodynamical analysis of 11,562 metal-rich, high-eccentricity halo-like main-sequence stars, which have been referred to as the Splash or Splashed Disk, selected from the Sloan Digital Sky Survey and Large Sky Area Multi-Object Fiber ...
