This is the first paper of the “Binarity at LOw Metallicity (BLOeM)” collaboration which targets to obtain spectra for about 1000 massive stars in the SMC! Apart from being an extremely interesting project it really matches many of the sources I have been working with in the SMC. So perfect …
From July 1 (2024) and for the next three months I will be closely working* with a Physics undergrad, named Simos Vlassis, who followed my Python course and wanted to dive into more interesting stuff with Python. Therefore, I found the opportunity to offer him the possibility to work on …
It is Friday night and only two days are left before another Summer School for Astrostatistics in Crete ! Everything is ready and I am excited for a totally new iteration of our school. I have to admit though that after three already successful events we have streamlined the process. …
Stephan extends the work he has performed previously in the Magellanic Clouds to RSGs identified in the ASSESS project in galaxies at subsolar metallicity. Investigating episodic mass loss in evolved massive stars: II. Physical properties of red supergiants at subsolar metallicity S. de Wit, A.Z. Bonanos, K. Antoniadis, E. Zapartas, …
This is a paper led by Kostas from the ASSESS team where we investigated the mass-loss in LMC/s RSGs. Interestingly this made its way to the astrobites site. Establishing a mass-loss rate relation for red supergiants in the Large Magellanic Cloud K. Antoniadis, A.Z. Bonanos, S. de Wit, E. Zapartas, …
The deadline for the 2024 iteration of the Summer School for Astrostatistics in Crete is approaching fast. We are excited to host this event, which actually starts to settle as an annual event. And why not since it seems there is a huge need in practical training in statistics and …
Paper II of the XShootU collaboration is finally accepted at A&A! That is a cornerstone paper for the collaboration since it presents the analysis of the observations and provides the final scientific products with which the whole collaboration (and everybody else) can work with. X-Shooting ULLYSES: Massive Stars at low …
I have been using Python almost 15 years now! Starting from 2, over 3 and the many advances in the meantime (e.g. astropy!). So, this semester (Sprint 2024) i will be teaching the course “Introduction to Python for Physicists” (F-254) at the University of Crete. This will be an intro …
A paper that collectively presents the results from our intensive observing campaign in the ASSESS project, focusing on the southern galaxies (a forthcoming paper will deal with the northern ones). Investigating episodic mass loss in evolved massive stars: I. Spectroscopy of dusty massive stars in ten southern galaxies A.Z. Bonanos, …
With increasing distance fainter stars, and therefore those of lower luminosity, older populations, become less observable. This means that with increasing distance we actually probe different parts of a Color-Magnitude diagram (CMD), which mainly consists of the brightest and more evolved massive stars. This is best shown in this figure …
