Between 26-28 of July (2023), I managed to participate in-person the 16th Hellenic Astronomical Conference, held in Athens. I personally contributed with one talk and one poster (long gone the days that I would submit two talks!), which was part of the ASSESS group’s contribution with another two talks, and …
Although I thought at the beginning that this would be a quick paper, it took considerable time to complete! Thanks a lot to Stephan that did significant work with figures I was able to focus on the text and the discussion. This is the first work to reveal B[e] Supergiants …
It was back in 2020 during the pandemic that the first call for the XShootU collaboration was sent. I had really little idea of what would follow, but I fount it definitely motivating to participate. Therefore I volunteer to help with the data reduction. After 2.5 years we are getting …

Here comes the announcement of the third (already!) iteration of our Summer School for Astrostatistics in Crete! This is an in-person meeting, as it focus on the practical use of statistics and machine learning in academic research. We will supply all the necessary guidelines through Astronomical problems. Check the website …
Getting observing time needs both a good proposal and some … luck! Although I have been into many proposals (with some of them written by me actually) I did not have the excitement to get it as PI. The time has finally come now!! At the current observing period of …
A proceedings paper from IAUS 366 that took place virtually back in October 2021 (for which I had another poster contribution) was finally published at the end of 2022. It summarizes a collective work led by Michaela on B[e] Supergiants and Yellow Hypergiants, two massive star phases where we observe …
The biggest issue when dealing with multiple projects is how to keep track of the various Python and other packages’ versions you are using in each project. It is not uncommon to update something and get something else broken… The solution is virtual environments. And for these there are few …
In the latest meeting of the Spanish Astronomical Society (5-9 September, Tenerife, Spain) it was announced that our work with Emmanuel (Manos) Kardasis on Venus’ Cloud Discontinuity (published at the beginning of 2022, in the journal Atmosphere) was the winner for the 2nd iteration of the Javier Gorosabel Award on …
Properties of luminous red supergiant stars in the Magellanic Clouds S. de Wit, A.Z. Bonanos, F. Tramper, M. Yang, G. Maravelias, K. Boutsia, N. Britavskiy, and E. Zapartas There is evidence that some red supergiants (RSGs) experience short lived phases of extreme mass loss, producing copious amounts of dust. These …
