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…
Advancing Astrophysics with the SKA II
Anna Bonaldi, Tyler L. Bourke, Philippa Hartley +45
Advancing Astrophysics with the SKA II (AASKAII), written by our science community, outlines the transformative scientific advances that will be enabled by the SKA telescopes. In t…
Advancing extragalactic spectral line studies with the Square Kilometre Array Observatory
Jacco Th. van Loon, Viviana Casasola, Manuela Bischetti +6
We present an overview of the Square Kilometre Array Observatory (SKAO) science potential in the area of extragalactic spectral lines besides 21-cm neutral hydrogen. It highlights…
Cosmic Rulers: Masers as Tools for Probing Structure in the Galaxy and Beyond, from AU to kpc
Kazi L. J. Rygl, Anna Bartkiewicz, Olga Bayandina +9
Maser emission provides an unique window into astronomical sources across vast spatial scales - from tens to hundreds of astronomical units around protostars and evolved stars up t…
Another one bites the dust -- how red supergiants keep surprising us
Jacco Th. van Loon
Extreme red supergiant WOH G64 has led researchers a merry dance these last few years, but what does it reveal about the secret lives of these beasts? This article sets the latest…
The unique capabilities of HST for stellar physics: Probing Atmospheric Structure, Chromospheres, and Mass Loss of Evolved Stars
Maryam Saberi, Graham Harper, Jacco Th. van Loon +10
Evolved stars are among the primary sources of chemical enrichment and dust production in galaxies. During the giant phases, stars return a substantial fraction of their mass to th…
