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".

The time evolution of the Milky Way’s oxygen abundance gradient [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 © 2018 The Author(s). We study the evolution of oxygen abundance radial gradients as a function of time for the Milky Way Galaxy obtained with our MulChem chemical evolution model. We review the recent data of abundances for different objects observed in

EVOLUTION OF MOLECULAR AND ATOMIC GAS PHASES IN THE MILKY WAY [PDF]
The Astrophysical Journal, 2016 We analyze radial and azimuthal variations of the phase balance between the molecular and atomic interstellar medium (ISM) in the Milky Way (MW) using archival CO(J = 1-0) and HI 21 cm data.

The AMBRE Project: Constraining the lithium evolution in the Milky Way [PDF]
Astronomy & Astrophysics, 2016 Context. The chemical evolution of lithium in the Milky Way represents a major problem in modern astrophysics. Indeed, lithium is, on the one hand, easily destroyed in stellar interiors, and, on the other hand, produced at some specific stellar ...

Milky Way globular clusters on cosmological timescales. I. Evolution of the orbital parameters in time-varying potentials [PDF]
Astronomy & Astrophysics, 2023 Context. Recent observational data show that the Milky Way (MW) galaxy contains about 170 globular clusters (GCs). A fraction of them is likely formed in dwarf galaxies accreted onto the MW in the past, while the remaining of clusters are formed in-situ.

Unveiling the time evolution of chemical abundances across the Milky Way disk with APOGEE [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Chemical abundances are an essential tool in untangling the Milky Way’s enrichment history. However, the evolution of the interstellar medium abundance gradient with cosmic time is lost as a result of radial mixing processes.

A simple model for the evolution of disc galaxies: The Milky Way [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 A simple model for the evolution of disc galaxies is presented. We adopt three numbers from observations of the Milky Way disc, the local surface mass density, the stellar scale length (of the assumedly exponential disc) and the amplitude of the ...

A comprehensive model for the formation and evolution of the faintest Milky Way dwarf satellites [PDF]
Monthly notices of the Royal Astronomical Society, 2023 In this study, we modify the semi-analytic model Galacticus in order to accurately reproduce the observed properties of dwarf galaxies in the Milky Way.

Great Balls of FIRE II: The evolution and destruction of star clusters across cosmic time in a Milky Way-mass galaxy [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The current generation of galaxy simulations can resolve individual giant molecular clouds, the progenitors of dense star clusters. But the evolutionary fate of these young massive clusters, and whether they can become the old globular clusters (GCs ...

Evolution of the local spiral structure of the Milky Way revealed by open clusters [PDF]
Astronomy & Astrophysics, 2021 The structure and evolution of the spiral arms of our Milky Way are basic but long-standing questions in astronomy. In particular, the lifetime of spiral arms is still a puzzle and has not been well constrained from observations.
