The critical role of HST UV spectroscopy in constraining red supergiant binary systems
Daniel Jadlovský, Andreas Sander, Lee Patrick +3
The Hubble Space Telescope (HST) has advanced our knowledge of stellar evolution thanks to its unique high-spectral resolution and high-sensitivity capabilities in the UV region, e…
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…
Hidden massive eclipsing binaries in red supergiant systems: The hierarchical triple system KQ Puppis and other candidates
D. Jadlovský, L. Molnár, A. Ercolino +26
The majority of massive stars are part of binary systems that may interact during their evolution. However, not many RSGs are known binaries, and only a few have constrained orbita…
The complex dependencies of Wolf-Rayet winds -- Insights from detailed radiative transfer models
Andreas A. C. Sander, Roel R. Lefever, Gemma González-TorÃ
With their emission-line dominated spectra, the appearance of Wolf-Rayet stars is shaped by their strong stellar winds. Yet, the physical mechanisms behind their high mass loss hav…
Dynamically consistent analysis of Galactic WN4b stars
Roel R. Lefever, Andreas A. C. Sander, Matheus Bernini-Peron +6
Many Wolf-Rayet (WR) stars have optically thick winds that cloak the hydrostatic layers of the underlying star. In these cases, traditional spectral analysis methods are plagued by…
Can Wolf-Rayet stars be the missing ingredient to explain high-z He II ionizing radiation?
G. González-TorÃ, A. A. C. Sander, E. Egorova +7
Classical Wolf-Rayet (WR) stars are hot, massive stars with depleted hydrogen. At low metallicities (Z), WN3-type WR stars have relatively thin winds and are major sources of ioniz…
