The 15th Gaia Science Alerts and ORP Time-Domain Workshop 2024 in Crete

At the beginning of October we had a great opportunity to present the latest results of our work with my MSc. student Stella Avgousti. The 15th Gaia Science Alerts and ORP Time-Domain Workshop 2024 was hosted by the Institute of Astrophysics – FORTH and for me – personally – it was perfect as it was placed in my town! So no need to travel (in the lack of any funding also…).

Since it was a Gaia related workshop and on variability it was an excellent place to showcase results form Stella’s work, which is to identify variable evolved massive stars using the Gaia Andromeda Photometric Survey combining predictions from the machine-learning classifier we have developed (Maravelias+2022, Maravelias in prep). Our findings including approximate 700 variable sources with some very interesting results such as a Luminous Blue Variable and characteristic light curves of Red Supergiants.

And on top of that, Alceste made it to the conference too! She presented our latest results on some of the most extreme Red Supergiants discovered in the ASSESS project.

More interestingly you can find our talks publicly on YouTube (check 1:07:55 for Alceste, and 1:23:35 for me).

It was really fortunate to have both Stella and Alceste in Heraklion, where we managed to spend some time discussing in person and not virtually.
