JWST survey of 72 young stars shows how planet-forming disks lose their gas

Provided decades of theoretical work underpinning the disk dispersal interpretation

The James Webb Space Telescope surveyed 72 young sun-like stars and found their planet-forming disks lose gas through two distinct wind mechanisms in sequence. Magnetic fields drive strong jets and molecular winds in the youngest systems, then high-energy starlight heats the thinning gas until it escapes in a process called photoevaporation.
