2D chemical evolution model: the impact of galactic disc asymmetries on azimuthal chemical abundance variations

E. Spitoni, G. Cescutti, I. Minchev +5

Galactic disc chemical evolution models generally ignore azimuthal surface density variation that can introduce chemical abundance azimuthal gradients. Recent observations, however…

The escape speed curve of the Galaxy obtained from Gaia DR2 implies a heavy Milky Way

Giacomo Monari, Benoit Famaey, Ismael Carrillo +6

We measure the escape speed curve of the Milky Way based on the analysis of the velocity distribution of counter-rotating halo stars from the Gaia DR2. The distances we…

The metal-rich halo component extended in z: a characterization with Gaia DR2 and APOGEE

Emma Fernández-Alvar, J. G. Fernández-Trincado, Edmundo Moreno +12

We report an analysis of the metal-rich tail ([Fe/H] ) of halo stars located at distances from the Galactic plane up to kpc, observed by the Apache Point…

How does the stellar disk of the Milky Way get its gas?

Sebastian E. Nuza, Cristina Chiappini, Cecilia Scannapieco +3

In chemodynamical evolution models it is usually assumed that the Milky Way galaxy forms from the inside-out implying that gas inflows onto the disk decrease with galactocentric di…

Chemodynamical history of the Galactic Bulge

B. Barbuy, C. Chiappini, O. Gerhard

The Galactic Bulge can uniquely be studied from large samples of individual stars, and is therefore of prime importance for understanding the stellar population structure of bulges…

Spiral arm crossings inferred from ridges in Gaia stellar velocity distributions

Alice C. Quillen, Ismael Carrillo, Friedrich Anders +7

The solar neighborhood contains disc stars that have recently crossed spiral arms in the Galaxy. We propose that boundaries in local velocity distributions separate stars that have…
