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 …
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, E. Christodoulou, G. Munoz-Sanchez, K. Antoniadis, S. Athanasiou, G. Maravelias, M. Yang, E. Zapartas The ASSESS project aims to determine the role of episodic mass-loss …
Gonzalo Munoz-Sanchez and Evangelia Christodoulou traveled this November to Chile, and more specifically to the ESO’s Very Large Telescope facility in Paranal. The purpose of their trip was to get the data for a project that was awarded ~1.5 nights at the very competitive FORS2 instrument. The goal was to …

Introducing the ASSESS project: Episodic Mass Loss in Evolved Massive Stars – Key to Understanding the Explosive Early Universe A.Z. Bonanos, G. Maravelias, M. Yang, F. Tramper, S. de Wit, E. Zapartas, K. Antoniadis, E. Christodoulou, G. Munoz-Sanchez Episodic mass loss is not understood theoretically, neither accounted for in state-of-the-art …
Over the last few weeks we have received some valuable help from two new students that joined our team. Anna Philippopoulou joined the team directly after high school and just before starting her studies in Physics at the University of Oxford (UK). She is helping with checking RSGs in NGC …
Another successful ESO proposal! We managed to get about 1.5 nights for cycle P112, and in visitor mode! So, now that we are free to travel, we will have the PhD students Gonzalo Munoz-Sanchez (PI of the project) and Evangelia Christodoulou to travel to Paranal and observe from there. The …
During 26-28 of July (2023), the ASSESS group actively participated in the 16th Hellenic Astronomical Conference, held in Athens. In total, we had three talks and five posters accepted. Alceste Bonanos provided an overview of the “Results of the ASSESS project: Episodic Mass Loss in Evolved Massive Stars: Key to …
