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 …
The International Conference on the Physics of Extreme Massive Stars took place on June 24-28 (2024) in Rio de Janeiro in Brazil. That was a great opportunity for our PhD students Gonzalo and Evangelia to present some of our most recent results in an international conference focused on topics such …
Between 9 – 15 of June (2024) the ASSESS team was in Crete to help with the materialization of the third iteration of Supernova Remnants conference, which becomes probably the most important point of reference for this particular field. However, it also intersects with ours since our targets of interest …

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 …
As we are actively working on a series of forthcoming papers, we are meticulously refining the final stages of data analysis and interpretation. Especially when encountering new and exciting results we must be careful to not overlook any potential issues. While our expertise in Red Supergiants is well-established, seeking additional …

Properties of luminous red supergiant stars in the Magellanic Clouds S. de Wit, A.Z. Bonanos, F. Tramper, M. Yang, G. Maravelias, K. Boutsia, N. Britavskiy, and E. Zapartas There is evidence that some red supergiants (RSGs) experience short lived phases of extreme mass loss, producing copious amounts of dust. These …
