The disk wind mainly removes gas from the disk, but dust particles are also swept away from the disk. This increases the dust-to-gas ratio and promotes the formation of solid particles and subsequently the formation of planetesimals. In a typical protoplanetary disk the low mass planets migrate inwards due to gravitational interactions with the ...
2MASS J04202144+2813491 (also known as Tau 042021) [3] [6] is an edge-on protoplanetary disk in the Taurus Molecular Cloud. [3]The star is hidden behind the edge-on disk. Early estimates found that it has a mass of 0.272 ±0.009 M ☉, [7] but a later study did find a higher mass of 0.3–0.4 M
Only some are transitional disks between protoplanetary and debris. A few disks in this list are circumbinary disks. List of large disks This ...
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 not be considered an accretion disk ; while the two are similar, an accretion disk is hotter and spins much faster.
Thus the formation of planetary systems is thought to be a natural result of star formation. A Sun-like star usually takes approximately 1 million years to form, with the protoplanetary disk evolving into a planetary system over the next 10–100 million years. [2] The protoplanetary disk is an accretion disk that feeds the central star. [3]
Radial drift is a process by which dust particles migrates in Protoplanetary disks during the formation of planetesimals.It involves the motion of solid particles within the gas-dominated environment surrounding a young star and is crucial to understanding the formation of planets from protoplanetary disks.
The Nice model, developed in the early 2000s, describes the dynamical evolution of the Solar System following the dissipation of the protoplanetary disk.It posits that the giant planets initially formed in a more compact configuration and subsequently migrated to their current orbits due to interactions with a massive disk of planetesimals.

His book Evolution of the protoplanetary cloud and formation of the Earth and the planets, [31] which was translated to English in 1972, had a long-lasting effect on how scientists thought about the formation of the planets. [32] In this book, almost all major problems of the planetary formation process were formulated, and some of them were ...
