disk evolution

Disk evolution refers to the process by which the spinning disks of gas and dust surrounding young stars change over time. Initially, these protoplanetary disks contain the material that can form planets, moons, and other celestial objects. As the disk ages, particles collide and stick together, gradually building larger bodies—planets and asteroids—while some material is blown away by stellar winds or absorbed into the star. Over millions of years, the disk disperses, leaving behind a system of planets and smaller objects, shaping the architecture of mature planetary systems.
