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…
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…
pySTARBURST99: The Next Generation of STARBURST99
Calum Hawcroft, Claus Leitherer, Oskar Arangure +8
STARBURST99 is a population synthesis code tailored to predict the integrated properties or observational characteristics of star-forming galaxies. Here we present an update to STA…
First JWST/NIRSpec Spectroscopy of O Stars in the Small Magellanic Cloud
Armin Mang Román, Peter Zeidler, Wolf-Rainer Hamann +10
Determining how much mass is removed by stellar winds is crucial to understanding massive star evolution and feedback. However, traditional spectroscopic diagnostics in the UV and…
X-Shooting ULLYSES: Massive stars at low metallicity VI. Atmosphere and mass-loss properties of O-type giants in the Small Magellanic Cloud
Frank Backs, S. A. Brands, A. de Koter +21
Mass loss through a stellar wind is an important physical process that steers the evolution of massive stars and controls the properties of their end-of-life products, such as the…
Hot Star Winds
Andreas A. C. Sander
The properties, impact, and fate of hot stars cannot be understood without considering their winds. Revealed to be an almost ubiquitous phenomenon in the regime of massive stars, t…
Gas-phase Fe/O and Fe/N abundances in Star-Forming Regions. Relations between nucleosynthesis, metallicity and dust
J. E. Méndez-Delgado, K. Kreckel, C. Esteban +10
In stars, metallicity is usually traced using Fe, while in nebulae, O serves as the preferred proxy. Both elements have different nucleosynthetic origins and are not directly compa…
Observations of Extremely Metal-Poor O Stars: Weak Winds and Constraints for Evolution Models
O. Grace Telford, John Chisholm, Andreas A. C. Sander +3
Metal-poor massive stars drive the evolution of low-mass galaxies, both locally and at high redshift. However, quantifying the feedback they impart to their local surroundings rema…
X-Shooting ULLYSES: Massive Stars at Low Metallicity
Jorick S. Vink, Paul Crowther, Alex Fullerton +20
The Hubble Space Telescope has devoted 500 orbits to observing 250 massive stars with low metallicity in the ultraviolet (UV) range within the framework of the ULLYSES program. The…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
Aperture and Resolution Effects on Ultraviolet Star-Forming Properties: Insights from Local Galaxies and Implications for High-Redshift Observations
Ilyse Clark, Danielle A. Berg, Claus Leitherer +2
We present an analysis of the effects of spectral resolution and aperture scales on derived galaxy properties using far-ultraviolet (FUV) spectra of local star-forming galaxies fro…
X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
