Marta Lorenzo successfully defended her PhD work on July 3rd, 2025, at the Universidad Autónoma de Madrid. Her thesis entitled ‘Sextans A, a Rosetta stone for massive star formation and evolution at extremely low metallicity’ obtained the maximum grade, Sobresaliente cum laude. Her work has laid out the foundations for future studies of very metal poor massive stars. Huge congratulations!

Aided by the latest, top-notch technologies, we are back at 100% office hours at CAB facilities. Regretfully we could not enforce social distance between laptops.

Finally the first work-visit after the pandemic unleashed! Our friends from the Instituto de Astrofísica de Canarias, Sergio Simón Díaz and Abel de Burgos, visited CAB in June. We discussed recent advances of the IACOB database and tools, progress on metal-poor massive stars, machine learning applied to massive stars, shortcomings of the state-of-the-art codes FASTWIND and CMFGEN,  and the possible expansions of the grid of FASTWIND models managed by the broad Spanish team of massive stars. Very productive days, and hopefully the first of many to come.

Miriam García and Artemio Herrero tell us about the role of metal-poor massive stars to interpret local and high redshift observations, intriguing open questions and prospect for the future. In Spanish!

The 2021 annual meeting of the European Astronomical Society will host a two-day long symposium on massive stars. Experts around the globe will meet online to discuss massive star formation, evolution, and the different mechanisms that can alter surface abundances.
