3D Insights into Globular Cluster Formation and Evolution
A groundbreaking study published in Astronomy & Astrophysics provides the first 3D kinematic analysis of multiple stellar populations in 16 globular clusters, revealing key insights into their formation and evolution. Conducted by researchers from INAF, the University of Bologna, and Indiana University, the study shows that globular clusters formed through multiple star formation events, with stars exhibiting distinct kinematic properties based on their chemical composition. This research, utilizing data from the ESA Gaia telescope and ESO VLT, offers a new framework for understanding these ancient cosmic structures.
