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…
The chemical fingerprint of the Gaia BH3 system. Evidence for early cluster enrichment from the analysis of 51 elements
Gregory Vanden Broeck, Thibault Merle, Nhat Tan Mai +5
The Gaia BH3 system hosts the most massive known stellar-origin black hole and a low-mass metal-poor companion whose chemical composition may constrain early explosive nucleosynthe…
Investigating non-LTE abundances of Neodymium (Nd) in metal-poor FGK stars
John D. Dixon, Rana Ezzeddine, Yangyang Li +3
The dominant site(s) of the -process are a subject of current debate. Ejecta from -process enrichment events like kilonovae are difficult to directly measure, so we must inst…
Barium isotopic ratios in metal-poor stars: calibrating the method with globular clusters
Riano E. Giribaldi, Laura Magrini, Jose Schiappacasse-Ulloa +2
Identifying the nucleosynthesis processes behind heavy-element enrichment in stellar atmospheres is challenging. It typically relies on comparing observed abundance-to-iron ratios…
