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…
A new long gamma-ray burst formation pathway at solar metallicity
M. M. Briel, T. Fragos, O. S. Salafia +11
Context. Long gamma-ray bursts (LGRBs) are generally observed in low-metallicity environments. However, 10 to 20 per cent of LGRBs at redshift are associated with near-solar…
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.…
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…
Investigating episodic mass loss in evolved massive stars: I. Spectroscopy of dusty massive stars in ten southern galaxies
A. Z. Bonanos, F. Tramper, S. de Wit +7
The ASSESS project aims to determine the role of episodic mass-loss in the evolution of massive stars. As a first step, we construct a catalog of spectroscopically identified dusty…
Evolved Massive Stars at Low-metallicity V. Mass-Loss Rate of Red Supergiant Stars in the Small Magellanic Cloud
Ming Yang, Alceste Z. Bonanos, Biwei Jiang +17
We assemble the most complete and clean red supergiant (RSG) sample (2,121 targets) so far in the Small Magellanic Cloud (SMC) with 53 different bands of data to study the MLR of R…
Properties of luminous red supergiant stars in the Magellanic Clouds
S. de Wit, A. Z. Bonanos, F. Tramper +5
There is evidence that some red supergiants (RSGs) experience short lived phases of extreme mass loss, producing copious amounts of dust. These episodic outburst phases help to str…
