An international team, led by a pre-doctoral researcher at the Instituto de Astrofísica de Canarias (IAC), has revealed that the heaviest chemical elements on the surfaces of the youngest massive stars originate from their more evolved companions. The study has been published in the journal Astronomy and Astrophysics . ‘Throughout their lives, stars produce energy by fusing lighter chemical elements into heavier ones.’ “Stars are the universe’s great factories for chemical elements: as they evolve, they take the lighter ones and fuse them into heavier ones, changing their originalAdvertised on -
El ciclo de charlas divulgativas Del Cielo a la Tesis, impulsado por el estudiantado predoctoral del Instituto de Astrofísica de Canarias (IAC) y la Universidad de La Laguna (ULL) para acercar la investigación en astrofísica a la ciudadanía, celebrará una nueva sesión el próximo 22 de enero de 2026 a las 16:30 horas en el Museo de la Ciencia y el Cosmos, del Organismo Autónomo de Museos y Centros del Cabildo de Tenerife.

Researchers from the Instituto de Astrofísica de Canarias (IAC), in collaboration with the Instituto de Ciencias del Cosmos de la Universidad de Barcelona (ICCUB) and the Instituto de Estudios Espaciales de Cataluña (IEEC), have carried out the largest observational study to date on massive runaway stars including rotation and binarity in the Milky Way. This work, recently published in Astronomy & Astrophysics , sheds light on how these stellar “fugitives” are launched into space and what their properties reveal about their intriguing origins. Runaway stars are stars that travel throughAdvertised on
