This year’s European Astronomical Society meeting was held at Cork, Ireland, between 23 and 27 of June (2025). One of the plenary talks was given by Alceste (Bonanos) on June 24th. Entitled “Episodic Mass Loss in Evolved Massive Stars”, she summarized what we have managed to discover and understand during …
Alceste Z. Bonanos Identifications of red supergiants (RSGs) in the Milky Way and nearby galaxies have experienced an exponential increase in recent years, driven by advancements in selection techniques, the continued expansion of archival datasets, and a steady increase in spectroscopic data. This review describes the advances in methodologies and …
S. de Wit, G. Muñoz-Sanchez, G. Maravelias, A.Z. Bonanos, K. Antoniadis, D. García-Álvarez, N. Britavskiy, A. Ruiz, A. Philippopoulou 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 understood. Here we report the …

Avgousti Mass loss is a key aspect of stellar evolution, particularly in evolved massive stars, yet episodic mass loss remains poorly understood. To investigate this, we need …
Last Friday, on March 21st just after the beginning of spring, Gonzalo successfully defended his PhD thesis entitled “Episodic mass loss in extreme Red Supergiants“. His work over the last 3+ years at the national Observatory of Athens included a ton of observations and spending a lot of time in …
