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 …
This is actually a preview of what will follow after the first paper of the machine-learning classifier. We put it into action to get predictions for a number of galaxies and we start exploring the results. Of more interest is the fractions of the populations with metallicity, although a more …
JWST delivered its first images (publicly) today! That was the best news to get as an astronomer for two reasons. The one is of course the scientific reasons, as it is one of the most important telescopes sent to space and perhaps the most challenging mission to launch and deploy …
In March I got invited to give a talk for the Thüringer Landessternwarte Tautenburg group. Back then June 21 looked like a far date in a relative relaxed time period. I was so wrong… they are so hectic days! Nevertheless, I managed to prepare a talk entitled: “The ASSESS classifier: …
Last night I was working on the laptop when naturally it asked for some power. Typically, when you plug in the power is should charge the battery, right? Well… no, it didn’t do that at all! And then dread start developing! What is wrong? Is it the plug, the connector …
Finally after two years of pandemic and two postponements of the IAU Symposium 361: “Massive Stars Near and Far” it was held in Ballyconnell, Ireland in the week of 8-13 May 2022. It was really a great opportunity. Not only I managed to meet in-person people and collaborators that I …
Following the success of the first Astrostatistics Summer School in Crete in 2019 (18-21 June), we now organize its second iteration (11-15 July). Initially scheduled for 2020, but we all now what happened and it was delayed. Now things to have matured so that we can actually repeat it and …
This is the first paper that results from my work with the ASSESS team over the last years. It focuses on the development of a machine-learning photometric classifier to characterize massive stars originating from IR (Spitzer) catalogs, which will help us understand the episodic mass loss. The first paper presents …
