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…
Assessing the performance of future space-based detectors: Astrophysical foregrounds and individual sources
Alice Perego, Matteo Bonetti, Alberto Sesana +2
The paper evaluates the detection capabilities of three proposed post‑LISA space‑based gravitational‑wave missions (μAres, AMIGO, and the Decihertz Observatory) by modeling astroph…
CHEOPS observations of V1298 Tau: updated planetary densities and implications on the early evolution of the young system
Hinna Shivkumar, Sérgio Gomes, Jean-Michel Désert +9
The young (10-30 Myr) multi-planet system V1298 Tau presents a unique opportunity to probe the early formation and evolution of young systems. We present new CHEOPS observations of…
The supernova Ia progenitor problem in the 2040s
Thomas Kupfer, Simone Scaringi, Ingrid Pelisoli +8
Type Ia supernovae (SNe Ia) are fundamental to cosmology and galactic chemical evolution, yet the nature of their progenitor systems remains unresolved. Multiple evolutionary pathw…
The final stages of binary evolution using multi-messenger studies
Thomas Kupfer, Simone Scaringi, Paul Groot +11
Ultracompact Galactic binaries with orbital periods below an hour are among the strongest persistent gravitational-wave (GW) sources in the mHz band and will constitute the dominan…
Hierarchical Triples vs. Globular Clusters: Binary black hole merger eccentricity distributions compete and evolve with redshift
Andris Dorozsmai, Isobel M. Romero-Shaw, Aditya Vijaykumar +5
The formation mechanisms of merging binary black holes (BBHs) observed by the LIGO-Virgo-KAGRA collaboration remain uncertain. Detectable eccentricity provides a powerful diagnosti…
