Young stars discovered in dwarf spheroidal galaxies confirm their recent infall into the Milky way
Francois Hammer, Piercarlo Bonifacio, Elisabetta Caffau +10
Recent observations from the ESA Gaia satellite and with the ESO VLT, have identified the presence of a population of young, 0.5 to 2 Gyr old, stars in the halo and in dwarf sphero…
Reviving old controversies: is the early Galaxy flat or round? Investigations into the early phases of the Milky Way formation through stellar kinematics and chemical abundances
P. Di Matteo, M. Spite, M. Haywood +4
We analyse a set of very metal-poor stars for which accurate chemical abundances have been obtained as part of the ESO Large Program "First stars" in the light of the Gaia DR2 data…
The disc origin of the Milky Way bulge: On the necessity of the thick disc
P. Di Matteo, F. Fragkoudi, S. Khoperskov +4
In the MW bulge, metal-rich stars form a strong bar and are more peanut-shaped than metal-poor stars. It has been recently claimed that this behavior is driven by the initial in-pl…
The disc origin of the Milky Way bulge: Dissecting the chemo-morphological relations using N-body simulations and APOGEE
F. Fragkoudi, P. Di Matteo, M. Haywood +4
There is a long-standing debate on the origin of the metal-poor stellar populations of the Milky Way (MW) bulge, with the two leading scenarios being that these populations are eit…
The age structure of stellar populations in the solar vicinity. Clues of a two-phase formation history of the Milky Way disk
M. Haywood, P. Di Matteo, M. Lehnert +2
We analyze high quality abundances data of solar neighborhood stars and show that there are two distinct regimes of [alpha/Fe] versus age which we identify as the epochs of the thi…
