Zero-metallicity hypernova uncovered by an ultra metal-poor star in the Sculptor dwarf spheroidal galaxy
Ása Skúladóttir, Stefania Salvadori, Anish M. Amarsi +9
Although true metal-free "Population III" stars have so-far escaped discovery, their nature, and that of their supernovae, is revealed in the chemical products left behind in the n…
Ultra-faint dwarf galaxies: unveiling the minimum mass of the first stars
Martina Rossi, Stefania Salvadori, Ása Skúladóttir
The non-detection of zero-metallicity stars in ultra-faint dwarf galaxies (UFDs) can be used to constrain the Initial Mass Function (IMF) of the first (PopIII) stars by means of a…
Neutron-capture elements in dwarf galaxies III: A homogenized analysis of 13 dwarf spheroidal and ultra-faint galaxies
Moritz Reichert, Camilla J. Hansen, Michael Hanke +3
We present a large homogeneous set of stellar parameters and abundances across a broad range of metallicities, involving classical dwarf spheroidal (dSph) and ultra-faint dSph…
Neutron-capture elements in dwarf galaxies I: Chemical clocks & the short timescale of the r-process
Ása Skúladóttir, Camilla Juul Hansen, Stefania Salvadori +1
The heavy elements (Z>30) are created in neutron-capture processes which happen at very different nucleosynthetic sites. To study them in an environment different from the Milky Wa…
Probing the existence of very massive first stars
S. Salvadori, P. Bonifacio, E. Caffau +4
We present a novel approach aimed at identifying the key chemical elements to search for the (missing) descendants of very massive first stars exploding as Pair Instability Superno…
4MOST Consortium Survey 2: The Milky Way Halo High-Resolution Survey
N. Christlieb, C. Battistini, P. Bonifacio +19
We will study the formation history of the Milky Way, and the earliest phases of its chemical enrichment, with a sample of more than 1.5 million stars at high galactic latitude. El…
