Udalski Red Supergiants (RSGs) are cool, evolved massive stars in the last evolutionary stage before exploding as a supernova. However, the most luminous RSGs may evolve blueward …
G. Munoz-Sanchez, S. de Wit , A. Z. Bonanos, K. Antoniadis, K. Boutsia, P. Boumis, E. Christodoulou, M. Kalitsounaki, and A. Udalski Context. Despite mounting evidence that extreme red supergiants (RSGs) undergo episodic mass-loss events, their role in RSG evolution remains uncertain. Critical questions remain unanswered, such as whether or …

Tsopela 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 …
K. Antoniadis, A.Z. Bonanos, S. de Wit, E. Zapartas, G. Munoz-Sanchez, G. Maravelias High mass-loss rates of red supergiants (RSGs) drastically affect their evolution and final fate, yet their mass-loss mechanism remains poorly understood. Various empirical prescriptions scaled with luminosity have been derived in the literature, yielding results with a …
