    IAC researchers participate in the largest Milky Way study of massive runaway stars
    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 through
