A young Saturnian planet orbiting a star in the stellar cluster IC 2602 described in the study: “TOI-837 b: Characterisation, formation, and evolutionary history of an infant warm Saturn-mass planet” of M. Damasso (INAF – OATo)

Analysis of TESS and HARPS observations confirms the existence of a Saturn-like planet orbiting a star associated with the young stellar cluster IC 2602   Stellar clusters are not only beautiful objects to photograph and observe through a telescope, but they also represent an important opportunity for studying stellar evolution. In fact, they are composed of rich samples of stars

The Gaia-ESO survey and the evolution of stellar clusters. Published on A&A “The Gaia-ESO Survey: kinematical and dynamical study of four young open clusters” of L. Bravi (INAF-OA Arcetri)

Despite the stars in our Galaxy typically formed in stellar clusters, only a small fraction of them today is observed associated with a cluster. This led to the conclusion that stellar clusters typically disperse in 10-100 million years. Two mechanisms are thought to be responsible for the dispersion of stellar clusters. According to the model of the “residual gas expulsion”,
