Evidence of ongoing radial migration in NGC 6754: Azimuthal variations of the gas properties
L. Sánchez-Menguiano, S. F. Sánchez, D. Kawata +9
Understanding the nature of spiral structure in disk galaxies is one of the main, and still unsolved questions in galactic astronomy. However, theoretical works are proposing new t…
A radial age gradient in the geometrically thick disk of the Milky Way
Marie Martig, Ivan Minchev, Melissa Ness +2
In the Milky Way, the thick disk can be defined using individual stellar abundances, kinematics, or age; or geometrically, as stars high above the mid-plane. In nearby galaxies, wh…
Cardinal kinematics: I. Rotation fields of the APOGEE Survey
Georges Kordopatis, Rosemary F. G. Wyse, Cristina Chiappini +3
Correlations between stellar chemistry and kinematics have long been used to gain insight into the evolution of the Milky Way Galaxy. Orbital angular momentum is a key physical par…
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…
Spiral-induced velocity and metallicity patterns in a cosmological zoom simulation of a Milky Way-sized galaxy
Robert J. J. Grand, Volker Springel, Daisuke Kawata +6
We use a high resolution cosmological zoom simulation of a Milky Way-sized halo to study the observable features in velocity and metallicity space associated with the dynamical inf…
Galactic Archaeology with asteroseismology and spectroscopy: Red giants observed by CoRoT and APOGEE
F. Anders, C. Chiappini, T. S. Rodrigues +42
With the advent of the space missions CoRoT and Kepler, it has become feasible to determine precise asteroseismic masses and ages for large samples of red-giant stars. In this pape…
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…
