HRMOS White Paper: Science Motivation
Laura Magrini, Thomas Bensby, Anna Brucalassi +52
The High-Resolution Multi-Object Spectrograph (HRMOS) is a facility instrument that we plan to propose for the Very Large Telescope (VLT) of the European Southern Observatory (ESO)…
Extremely metal-poor stars in the Fornax and Carina dwarf spheroidal galaxies
R. Lucchesi, P. Jablonka, Á. Skúladóttir +6
We present our analysis of VLT/UVES and X-shooter observations of six very metal-poor stars, including four stars at [Fe/H] in the Fornax and Carina dwarf spheroidal (…
True Pair-instability Supernova Descendant: Implications for the First Stars' Mass Distribution
Ioanna Koutsouridou, Stefania Salvadori, Ása Skúladóttir
The initial mass function (IMF) of the first Pop III stars remains a persistent mystery. Their predicted massive nature implies the existence of stars exploding as pair-instability…
The energy distribution of the first supernovae
I. Koutsouridou, S. Salvadori, Á. Skúladóttir +3
The nature of the first Pop III stars is still a mystery and the energy distribution of the first supernovae is completely unexplored. For the first time we account simultaneously…
First stars signatures in high-z absorbers
Stefania Salvadori, Valentina D'Odorico, Andrea Saccardi +2
The first stars were likely more massive than those forming today and thus rapidly evolved, exploding as supernovae and enriching the surrounding gas with their chemical products.…
A 3D view of dwarf galaxies with Gaia and VLT/FLAMES I. The Sculptor dwarf spheroidal
Eline Tolstoy, Ása Skúladóttir, Giuseppina Battaglia +12
We present a new homogeneous survey of VLT/FLAMES LR8 line-of-sight radial velocities (vlos) for 1604 resolved red giant branch stars in the Sculptor dwarf spheroidal galaxy. In ad…
On the dearth of C-enhanced metal-poor stars in the Galactic bulge
Giulia Pagnini, Stefania Salvadori, Martina Rossi +3
The chemical fingerprints of the first stars are retained within the photospheres of ancient unevolved metal-poor stars. A significant fraction of these stellar fossils is represen…
Understanding the origin of CEMP-no stars through ultra-faint dwarfs
Martina Rossi, Stefania Salvadori, Ása Skúladóttir +1
The origin of Carbon Enhanced Metal-Poor (CEMP-no) stars with low abundances of neutron-capture elements is still unclear. These stars are ubiquitous, found primarily in the Milky…
PISN-explorer: hunting the descendants of very massive first stars
D. S. Aguado, S. Salvadori, A. Skúladóttir +6
The very massive first stars () were fundamental to the early phases of reionization, metal enrichment, and super-massive black hole formation. Among them, thos…
