The internal kinematics and chemistry of 20 Milky Way strings
C. Boeche, A. Vallenari, J. Alonso-Santiago +8
Context: the recent discovery of filamentary stellar structures in the Milky Way disk raises the question of their formation in the context of the Galaxy evolution. Aims: in this w…
The Isotopic and Elemental Abundances of Planet-Host Star TRAPPIST-1
Darío González Picos, Ian J. M. Crossfield, David Coria +6
Elemental and isotopic abundances are key tracers of planet formation, stellar evolution, and Galactic chemical evolution. Very low-mass stars are particularly interesting in this…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
TOPoS VII. Age-metallicity relation in the Galactic halo and assembly of the Milky Way
P. Bonifacio, Y. Lebreton, I. Koutsouridou +8
One technique for determining stellar ages is to compare the position of a star in the Hertzsprung-Russell diagram to theoretical stellar evolutionary tracks. The sub-giant evoluti…
Limited imprint of high-mass IMF variations on sodium abundances in main-sequence galaxies
Ziyi Guo, Donatella Romano, Zhiqiang Yan +10
Growing evidence suggests that the stellar initial mass function (IMF) varies systematically across galaxies, deviating from the canonical Milky Way form. Such variations would mod…
Bulge Fossil Fragments as a new population of factories of gravitational wave sources in the Galaxy
F. R. Ferraro, E. Vesperini, B. Lanzoni +9
The discovery of the complex stellar populations hosted in two massive stellar systems in the Galactic bulge, namely Terzan5 and Liller 1, posed intriguing questions about their or…
