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 …
Discovering New B[e] Supergiants and Candidate Luminous Blue Variables in Nearby Galaxies Grigoris Maravelias, Stephan de Wit, Alceste Z. Bonanos, Frank Tramper, Gonzalo Munoz-Sanchez and Evangelia Christodoulou Mass loss is one of the key parameters that determine stellar evolution. Despite the progress we have achieved over the last decades we …

The 2023 version of the VFTS meeting was held in Max Planck Institute for Astrophysics in Garching for three days in March (27-29). Like last year’s meeting the ASSESS team was there to discuss our recent findings. This time though the representation was broader with more members of the group …
About a year ago Stathis Athanasiou joined our team to work on cross-matching sources from the Hubble Space Telescope to those detected from the ASSESS observations. After a whole year of efforts he managed to complete his thesis and defend it successfully ! Details of the thesisTitle: Mass-loss rates of …
For our observing needs we require the largest and the most modern facilities in both hemispheres (to obtain data for both our Southern and Northern galaxies in our sample). For this reason we have managed to achieve time at both GTC and ESO telescopes. For the period P111 of ESO …
