A few weeks ago (May 14, 2024), Stefan successfully defended his PhD thesis entitled “Physical parameters of red supergiants in nearby galaxies” which summarized his work over the last four years within the ASSESS project. This has resulted already in two major publications as first author (one published, one accepted) …

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 …
Our successful record of observing proposal continues also in 2024! We managed to obtain highly competitive observing time in two of the largest facilities in the world. We are going to use the FORS2 instrument at 8.2m ESO/VLT, as well as OSIRIS at 10.4m GTC. The granted time is ~17.5 …
