The Milky Way has no in-situ halo other than the heated thick disc. Composition of the stellar halo and age-dating the last significant merger with Gaia DR2 and APOGEE
P. Di Matteo, M. Haywood, M. D. Lehnert +5
Previous studies based on the analysis of Gaia DR2 data have revealed that accreted stars, possibly originating from a single progenitor satellite, are a significant component of t…
In disguise or out of reach: first clues about in-situ and accreted stars in the stellar halo of the Milky Way from Gaia DR2
Misha Haywood, Paola Di Matteo, Matthew Lehnert +3
We investigate the nature of the double color-magnitude sequence observed in the Gaia DR2 HR diagram of stars with high transverse velocities. The stars in the reddest-color sequen…
Phylogeny of the Milky Way's inner disk and bulge populations: Implications for gas accretion, (the lack of) inside-out thick disk formation, and quenching
Misha Haywood, Paola Di Matteo, Matthew Lehnert +3
We show that the bulge and the disk of the Milky Way (MW) at R7~kpc are well described by a unique chemical evolution and a two-phase star-formation history (SFH). We arg…
