A new study led by Professor Paolo Padoan has found that stars' disks might grow bigger over time due to Bondi-Hoyle accretion, contrary to previous beliefs.
Stars, even after formation, can continue to pull in material from surrounding gas clouds, adding mass to their disks and helping them become larger and longer-lasting.
Powerful computer simulations and theoretical models were used to explore how stars interact with their surroundings, with a focus on how turbulence affects material gathering.
This discovery explains the large sizes of planet-forming disks observed in space, providing new insights into the formation of planets, including possibly habitable ones.
