Reassessing the low- massive sequence stars in Gaia RVS
G. Nandakumar, G. Kordopatis, M. Schultheis +4
Recently, a chemically depleted young massive stellar population was identified using the spectroscopic catalogue of Gaia DR3. To explain its characteristics, a recent enhanced sta…
The effects of yields from binary massive stars as functions of metallicity
E. Pepe, E. Spitoni, F. Matteucci +1
Massive stars in binary systems that undergo mass transfer during their lifetime have a different evolution from that of single stars, possibly affecting their chemical yields. Whi…
Co-evolution of the Milky Way high- and low-α sequences with chemical evolution models
V. Grisoni, E. Spitoni, F. Matteucci
Observational data have revealed a clear dichotomy in the [α/Fe] vs. [Fe/H] diagram of the Milky Way thick and thin disc stars. Many recent studies have shown evidences of a co-evo…
The time-delay model and its applications to galactic archaeology
Francesca Matteucci
The time-delay model is the way we interpret the diagram [X/Fe] vs. [Fe/H], where X is the abundance of a generic element from carbon to uranium. This interpretation is based on th…
The chemical DNA of the Magellanic Clouds VI. Origin and evolution of neutron-capture elements in the SMC
Marco Palla, Alessio Mucciarelli, Donatella Romano +2
Context. In the context of galactic archaeology, the study of the Small Magellanic Cloud (SMC) is of crucial importance, as it represents a unique opportunity to study a nearby mas…
On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
Elemental abundance ratios for the bulge of M31
F. La Barbera, A. Vazdekis, F. Matteucci +3
We present radial trends of metallicity ([Fe/H]) and abundance ratios ([X/Fe]) for several chemical elements -- including C, N, Na, and the so-called alpha-elements (O, Mg, Si, Ca,…
Modelling chemical clocks -- Theoretical evidences of the space and time evolution of [s/alpha] in the Galactic disc with Gaia-ESO survey
Marta Molero, Laura Magrini, Marco Palla +6
Chemical clocks based on [s-process elements/alpha-elements] ratios are widely used to estimate ages of Galactic stellar populations. However, the [s/alpha] vs. age relations are n…
Yields from massive stars in binaries. Chemical evolution of the Milky Way disk
E. Pepe, M. Palla, F. Matteucci +1
A large fraction of massive stars in the Galaxy reside in binary systems and their evolution is different from that of single stars. The yields of massive stars, which are the main…
Mapping radial abundance gradients with Gaia-ESO open clusters: Evidence of recent gas accretion in the Milky Way disk
Marco Palla, Laura Magrini, Emanuele Spitoni +5
Context. Recent evidences from spectroscopic surveys point towards the presence of a metal-poor, young stellar population in the chemical thin disk. In this context, the investigat…
The AMBRE Project: Lead abundance in Galactic stars
G. Contursi, P. de Laverny, A. Recio-Blanco +4
The chemical evolution of neutron capture elements in the Milky Way is still a matter of debate. Although more and more studies investigate their chemical behaviour, there is still…
Neutrino-driven Core-collapse Supernova Yields in Galactic Chemical Evolution
Finia P. Jost, Marta Molero, Gerard Navó +3
We provide yields from 189 neutrino-driven core-collapse supernova (CCSN) simulations covering zero-age main sequence masses between 11 and 75 solar masses and three different meta…
Near-infrared spectroscopic observations of massive young stellar object candidates in the Central Molecular Zone
G. Nandakumar, M. Schultheis, A. Feldmeier-Krause +6
We present a spectroscopic follow-up of photometrically-selected young stellar object (YSO) candidates in the Central Molecular Zone of the Galactic center. Our goal is to quantify…
The Galactic habitable zone around M and FGK stars with chemical evolution models with dust
E. Spitoni, L. Gioannini, F. Matteucci
The Galactic habitable zone is defined as the region with highly enough metallicity to form planetary systems in which Earth-like planets could be born and might be capable of sust…
Fluorine in the Solar neighborhood: No evidence for the neutrino process
H. Jönsson, N. Ryde, E. Spitoni +5
Asymptotic Giant Branch stars are known to produce `cosmic' fluorine but it is uncertain whether these stars are the main producers of fluorine in the Solar neighborhood or if any…
The Effects of radial inflow of gas and galactic fountains on the chemical evolution of M31
E. Spitoni, F. Matteucci, M. M. Marcon-Uchida
Galactic fountains and radial gas flows are very important ingredients in modeling the chemical evolution of galactic disks. Our aim here is to study the effects of galactic founta…
