Does the chemical signature of TYC 8442-1036-1 originate from a rotating massive star that died in a faint explosion?
G. Cescutti, M. Valentini, P. François +4
Context. We have recently investigated the origin of chemical signatures observed in Galactic halo stars by means of a stochastic chemical evolution model. We have found that rotat…
Red giants observed by CoRoT and APOGEE: The evolution of the Milky Way's radial metallicity gradient
F. Anders, C. Chiappini, I. Minchev +21
Using combined asteroseismic and spectroscopic observations of 418 red-giant stars close to the Galactic disc plane (6 kpc kpc, kpc), w…
The relationship between mono-abundance and mono-age stellar populations in the Milky Way disk
I. Minchev, M. Steinmetz, C. Chiappini +4
Studying the Milky Way disk structure using stars in narrow bins of [Fe/H] and [alpha/Fe] has recently been proposed as a powerful method to understand the Galactic thick and thin…
Self-similarity in the chemical evolution of galaxies and the delay time distribution of SNe Ia
C. J. Walcher, R. M. Yates, I. Minchev +7
Recent improvements in the age dating of stellar populations and single stars allow us to study the ages and abundance of stars and galaxies with unprecedented accuracy. We here co…
The Gaia-ESO Survey: Revisiting the Li-rich giant problem
A. R. Casey, G. Ruchti, T. Masseron +48
The discovery of lithium-rich giants contradicts expectations from canonical stellar evolution. Here we report on the serendipitous discovery of 20 Li-rich giants observed during t…
Milky Way chemo-dynamics in the era of Gaia
I. Minchev, C. Chiappini, M. Martig
The main goal of Galactic Archaeology is understanding the formation and evolution of the basic Galactic components. This requires sophisticated chemo-dynamical modeling, where dis…
