The accretion history of the Milky Way IV. Hints of recent star formation in Milky Way dwarf spheroidal galaxies
Yanbin Yang, Elisabetta Caffau, Piercarlo Bonifacio +3
Dwarf spheroidal galaxies are known to be dominated by old stellar populations. This has led to the assumption that their gas-rich progenitors lost their gas during their infall in…
The accretion history of the Milky Way. II. Internal kinematics of globular clusters and of dwarf galaxies
Francois Hammer, Jianling Wang, Gary A. Mamon +7
We study how structural properties of globular clusters and dwarf galaxies are linked to their orbits in the Milky Way halo. From the inner to the outer halo, orbital energy increa…
Extremely metal-poor stars: the need for UV spectra
P. Bonifacio, E. Caffau, M. Spite
Our current understanding of the chemical evolution of the Universe is that a first generation of stars was formed out of primordial material, completely devoid of metals (Pop III…
The Pristine survey II: a sample of bright stars observed with FEROS
E. Caffau, P. Bonifacio, E. Starkenburg +8
Extremely metal-poor (EMP) stars are old objects formed in the first Gyr of the Universe. They are rare and, to select them, the most successful strategy has been to build on large…
