• Massivas-Torrejón lands in IAUS402

    September 2025. Our team members travel to Ensenada (Mexico) to attend the IAU symposium “Massive Stars Across Redshifts in the Era of JWST and Large-Scale Surveys“, for which Miriam Garcia has served as SOC co-chair. During one week, IAUS402 will bring together experts on different aspects of massive stars, and on high redshift star-forming galaxies and re-ionization. There will be discussion on the advances enabled by JWST and by large spectroscopic surveys, with an outlook of future advances to be powered by present and future observing facilities. Our team contributions to the field will be presented in one invited talk by Frank Tramper, contributed talks by Alex Legault and Miriam Garcia, and one poster.

  • A new Doctor on metal-poor massive stars!

    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!

  • Massivas-Torrejón back on-site!

    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.

  • Our colleagues from the IAC visit CAB

    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.

  • Metal-poor massive stars at the summer edition of the bulletin of the Spanish Astronomical Society

    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!
