The Fall of a Giant. Chemical evolution of Enceladus, alias the Gaia Sausage [PDF]
, 2019 We present the first chemical evolution model for Enceladus, alias the Gaia Sausage, to investigate the star formation history of one of the most massive satellites accreted by the Milky Way during a major merger event.

A grid of chemical evolution models along the Hubble Sequence [PDF]
, 2001 We have computed a grid of multiphase chemical evolution models whose results are valid for any spiral galaxy, using as input the maximum rotation velocity and the morphological type or index T.Comment: 2 pag., contribution to the conference Cosmic ...

Short-lived Radionuclides in the Milky Way Galaxy [PDF]
EPJ Web of Conferences, 2023 The short-lived radionuclides (SLRs) have a half-life ≤ 100 Myr. The γ-ray observations and excess abundance of their daughter nuclides in various meteoritic phases confirm the existence of SLRs in the Galaxy and early solar system (ESS), respectively ...

The Chemical Evolution of the Galaxy [PDF]
Symposium - International Astronomical Union, 1985 Over the last few years, our picture of the chemical evolution of the Galaxy has changed substantially. These changes are of interest because chemical evolution provides a common point of contact for most astrophysical processes of importance to galaxy evolution.

He abundances in disc galaxies. I. Predictions from cosmological chemodynamical simulations [PDF]
, 2019 Accepted for publication in A&AWe investigate how the stellar and gas-phase He abundances evolve as a function of time within simulated star-forming disc galaxies with different star formation histories.

Effects of thermohaline instability and rotation-induced mixing on the evolution of light elements in the Galaxy : D, 3He and 4He [PDF]
, 2012 Recent studies of low- and intermediate-mass stars show that the evolution of the chemical elements in these stars is very different from that proposed by standard stellar models.

On the α/Fe Bimodality of the M31 Disks
The Astrophysical Journal Letters, 2023 An outstanding question is whether the α /Fe bimodality exists in disk galaxies other than in the Milky Way. Here we present a bimodality using our state-of-the-art galactic chemical evolution models that can explain various observations in the Andromeda

A High-precision Survey of the D/H Ratio in the Nearby Interstellar Medium
The Astrophysical Journal, 2023 We present high signal-to-noise ratio measurements of the H i Ly α absorption line toward 16 Galactic targets that are at distances between approximately 190 and 2200 pc, all beyond the wall of the Local Bubble.

The Astrophysical Journal, 2023 Growing evidence in support of a connection between active galactic nuclei (AGN) activity and the ram pressure stripping (RPS) phenomenon has been found both observationally and theoretically in the past decades.
