JWST reveals a highly ionized nebula powered by an ultraluminous X-ray source with a massive black hole in the metal-poor galaxy Holmberg II
F. A. Fogantini, P. Zeidler, L. M. Oskinova +9
Recent James Webb Space Telescope (JWST) observations have revealed fine-structure lines of ions with ionization potentials \,eV, such as [Ne\,{\sc v}] and [O\,{\sc iv…
Mapping Wolf-Rayet winds with spectro-interferometry I. Detection of multiple co-rotating interaction regions in WR 6
K. Deshmukh, A. -N. Chené, A. J. Frost +8
WR 6 is the prototype for periodic variability due to large-scale wind structures in Wolf-Rayet (WR) stars, showing a consistent periodicity of 3.76 d in photometry, spectroscopy,…
Massive stars in the SDSS-V survey: New O2 stars in the Large Magellanic Cloud
A. Roman-Lopes, J. G. Fernández-Trincado, Marina Kounkel +7
{O2 stars define the hottest end of the normal O-star sequence, but their identification requires blue-optical nitrogen diagnostics absent from many surveys.} {We reassess three lu…
Distinct Population of Wolf-Rayet Stars in the Low-Metallicity Galaxy NGC 6822. Quantitative analysis of optical and UV spectra of the complete sample
R. Trigg, L. M. Oskinova, W. -R. Hamann +9
Context: Wolf-Rayet (WR) stars are particularly rare in low-metallicity galaxies and remain poorly understood. Detailed studies of the presumably complete population of WR stars in…
Potsdam Wolf-Rayet stellar atmosphere grids of OB-type stars: I. Spectroscopic temperature diagnostics across metallicity
D. Pauli, H. Todt, W. -R. Hamann +5
Massive hot stars are among the major ionizing sources in the Universe. The ionizing flux of a star strongly depends on its temperature, which is best measured spectroscopically us…
Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…
