The Stellar Winds Atlas II: Black Hole Formation at Solar Metallicity
Amedeo Romagnolo, Floor S. Broekgaarden, Alex C. Gormaz-Matamala +7
The paper builds a comprehensive grid of stellar evolution models to compare 14 wind prescriptions and shows that black‑hole masses at solar metallicity are determined by whether a…
A machine-learning photometric classifier for massive stars in nearby galaxies II. The catalog
G. Maravelias, A. Z. Bonanos, K. Antoniadis +8
Mass loss is a key aspect of stellar evolution, particularly in evolved massive stars, yet episodic mass loss remains poorly understood. To investigate this, we need evolved massiv…
The dramatic transition of the extreme Red Supergiant WOH G64 to a Yellow Hypergiant
G. Munoz-Sanchez, M. Kalitsounaki, S. de Wit +8
Red Supergiants (RSGs) are cool, evolved massive stars in their final evolutionary stage before exploding as a supernova. However, the evolution and fate of the most luminous RSGs…
A homogeneous view of asymptotic giant branch carbon stars as seen by Gaia
Alessio Liberatori, Despina Hatzidimitriou, Konstantinos Antoniadis +12
Carbon stars on the asymptotic giant branch are major contributors to galactic dust enrichment, with gas mass-loss rates up to 1e-4 Msun/yr. We present a homogeneous spectral energ…
The Stellar Winds Atlas I: Current uncertainties in mass-loss rates
Amedeo Romagnolo, Floor S. Broekgaarden, Konstantinos Antoniadis +1
Stellar winds are a major source of uncertainty in understanding the life and deaths of massive stars. Across studies in the field, prescriptions for stellar winds differ substanti…
Investigating episodic mass loss in evolved massive stars IV. Comprehensive analysis of dusty red supergiants in NGC 6822, IC 10, and WLM
E. Christodoulou, S. de Wit, A. Z. Bonanos +6
Mass loss shapes the fate of massive stars; however, the physical mechanism causing it remains uncertain. We present a comprehensive analysis of seven red supergiants, for which we…
