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.

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 ...

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 ...

A Computer Vision Milky Way Compass
, 2023 The Milky Way is used by nocturnal flying and walking insects for maintaining heading while navigating. In this study, we have explored the feasibility of the method for machine vision systems on autonomous vehicles by measuring the visual features and ...

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 ...

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 ...
