Unveiling the Power of Young Star Clusters with Gaia's Help

Young star clusters release energy through stellar winds, potentially driving cosmic ray production and gamma-ray emission. Using Gaia DR2 data, researchers estimated the mass and wind luminosity of 387 clusters, finding values up to significant particle acceleration and gamma-ray production. This study highlights the role of stellar winds in high-energy astrophysics and provides a foundation for further exploration of particle acceleration in the galaxy.
