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
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”,
