The Stellar Winds Atlas II: Black Hole Formation at Solar Metallicity
Amedeo Romagnolo, Floor S. Broekgaarden, Alex C. Gormaz-Matamala +7
Stellar winds are a primary source of uncertainty in predicting the masses of black holes (BHs) from massive stars. At solar metallicity, theoretical models lead to widely divergen…
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…
Investigating episodic mass loss in evolved massive stars: III. Spectroscopy of dusty massive stars in three northern galaxies
S. de Wit, G. Muñoz-Sanchez, G. Maravelias +6
Mass loss in massive stars is crucial to understanding how these stars evolve and explode. Despite increasing evidence indicating its importance, episodic mass loss remains poorly…
Investigating the metallicity dependence of the mass-loss rate relation of red supergiants
K. Antoniadis, E. Zapartas, A. Z. Bonanos +8
Red supergiants (RSGs) are cool and evolved massive stars exhibiting enhanced mass loss compared to their main sequence phase, affecting their evolution and fate. However, the theo…
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…
The effect of mass loss in models of red supergiants in the Small Magellanic Cloud
E. Zapartas, S. de Wit, K. Antoniadis +16
The rate and mechanism of mass loss of red supergiants (RSGs) remain poorly understood, especially at low metallicities. Motivated by the new empirical prescription by Yang et al.…
Episodic mass loss in the very luminous red supergiant [W60] B90 in the Large Magellanic Cloud
G. Munoz-Sanchez, S. de Wit, A. Z. Bonanos +6
This study delves into [W60] B90, one of the most luminous and extreme Red Supergiants (RSGs) in the Large Magellanic Cloud (LMC), aiming to search for evidence of episodic mass lo…
Investigating episodic mass loss in evolved massive stars: II. Physical properties of red supergiants at subsolar metallicity
S. de Wit, A. Z. Bonanos, K. Antoniadis +8
Mass loss during the red supergiant (RSG) phase plays a crucial role in the evolution of an intermediate massive star, however, the underlying mechanism remains unknown. We aim to…
Establishing a mass-loss rate relation for red supergiants in the Large Magellanic Cloud
K. Antoniadis, A. Z. Bonanos, S. de Wit +3
The high mass-loss rates of red supergiants (RSGs) drastically affect their evolution and final fate, but their mass-loss mechanism remains poorly understood. Various empirical pre…
