Implications of modern mass-loss rates for massive stars
JD Merritt, Simon Stevenson, Andreas Sander +7
Massive stars lose a significant fraction of their mass through stellar winds at various stages of their lives, including on the main sequence, during the red supergiant phase, and…
Massive Stars in the Thirties: awaiting new Hubble discoveries
Lidia M. Oskinova, Sylvia Ekström, Miriam Garcia +4
Massive stars play a fundamental role in shaping the evolution of galaxies through feedback, chemical enrichment, and their end products as neutron stars and black holes. Despite m…
Little Red Dots as Globular Clusters in Formation
John Chisholm, Danielle A. Berg, Michael Boylan-Kolchin +7
Little Red Dots (LRDs), among the most enigmatic high-redshift discoveries by JWST, are commonly believed to be powered by accreting supermassive black holes. Here, we explore the…
Open Questions in Massive Star Research across Cosmic Scales
Andreas A. C. Sander
Massive stars are the engines of the Cosmos, shaping their environments and driving galaxy evolution across cosmic time. Yet, this general textbook picture faces many challenges wh…
Sailing to the next safe harbour in our trip to the early Universe: The massive star population of metal-poor galaxies
N. Castro, M. Garcia, A. Herrero +5
Very metal-poor massive stars in the Local Group are our best proxies for the Universe's first stars, making them essential for modeling reionization and early galactic chemical ev…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
