WebNov 10, 2016 · The seeds of planet formation occur under a shroud of dust and gas, within a young star’s protoplanetary disk. As planets form and as the star ignites fusion and brightens, the gas is dispersed, leaving behind a debris disk of dust, planetesimals, and full-blown planets. But change doesn’t happen all at once. WebA protoplanetary disk is a disk of gas (99% by mass) and dust (1%), orbiting a newly formed star, from which planets are (hypothesized to be) formed.

These results provide a hypothesis for a novel view of disk evolution.
