Solar system formation protoplanetary disk

The nebular hypothesis of solar system formation describes how protoplanetary disks are thought to evolve into planetary systems. Electrostatic and gravitational interactions may cause the dust and ice grains in the disk to accrete into planetesimals. This process competes against the stellar wind, … See more A protoplanetary disk is a rotating circumstellar disc of dense gas and dust surrounding a young newly formed star, a T Tauri star, or Herbig Ae/Be star. The protoplanetary disk may also be considered an See more Gas-poor disks of circumstellar dust have been found around many nearby stars—most of which have ages in the range of ~10 million … See more • Accretion disk • Circumplanetary disk – Accumulation of matter around a planet • Debris disk See more Protostars form from molecular clouds consisting primarily of molecular hydrogen.
