Stars serve as the fundamental building blocks of galaxies and, by extension, the entire observable universe. Among the diverse spectrum of stars, those with a mass exceeding 8 times that of the Sun are labeled as massive stars. Their potent radiation and formidable stellar winds exert a significant
Inside these stars, elements beyond hydrogen and helium are formed, playing a pivotal role in the chemical transformation of galaxies and laying the foundation for life’s emergence. Furthermore, when these stars meet their end as supernovae, they give rise to neutron stars and black holes of stellar mass. All of this implies that their nature and evolution are critical for astrophysics.
In the published study observations have been taken of some 750 blue supergiant stars in a volume within 6,500 light-years of Earth, which makes this one of the most complete and highest quality samples obtained until now. For this study, the project IACOB of the Image of the Milky Way with the blue supergiant stars from the sample superposed. Credit: DSS/Abel de Burgos Sierra
