Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
The BLOeM campaign presents the first large‑scale spectroscopic survey of 929 massive stars in the Small Magellanic Cloud, revealing a high intrinsic binary fraction (>70%) among m…
Fast Dynamical Modelling of Milky Way Globular Clusters -- I. Implications for Initial Cluster Densities
Nolan Dickson, Vincent Hénault-Brunet, Fotios Fronimos Pouliasis +2
We infer the initial conditions of Milky Way (MW) globular clusters (GCs) from present-day observations, through the coupling of recently updated rapid cluster evolution models wit…
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…
-body modelling of the ED-2 stream progenitor shows Gaia BH3's formation involved dynamical interactions
Daniel MarÃn Pina, Mark Gieles, Sara Rastello +3
Context. The Gaia collaboration announced the discovery of a binary of a massive black hole (33 M) with a low-mass giant star (Gaia BH3) in the ED-2 stellar stream. The pro…
Hide and Seek with Gaia. Detectability of Predicted Thin-Disc Metal-Rich RR Lyrae Binaries in Gaia DR3 and DR4
Giuliano Iorio, Pranav Nagarajan, Alexey Bobrick +8
RR Lyrae stars (RRLs) are classical tracers of old stellar populations, yet growing evidence suggests the presence of a metal-rich ([Fe/H]>-0.5), intermediate-age (2-7 Gyr) sub-pop…
cBHBd: A fast code for the evolution of tidally limited star clusters and their binary black hole mergers
Fotios Fronimos Pouliasis, Nolan Dickson, Daniel MarÃn Pina +3
The evolution of star clusters is driven by stellar mass loss, two-body relaxation, and evaporation in the Galactic tidal field. Fast modeling tools are crucial for exploring diver…
