Disk instability theory
WebThe Disk Instability model predicts gravitational instabilities in the disk, causing the fast collapse of clumps that contract to form planet cores. This process would take just thousands of years. NAI scientist Alan Boss of the Carnegie Institute of Washington, D.C., a proponent of the Disk Instability theory, is tackling the computationally ... WebMay 4, 2024 · According to the disk instability hypothesis, a particularly massive protoplanetary disk that’s far enough away from the parent star is cool and large enough for portions of it to collapse under their own gravity, forming spiral arms. ... This was welcome news to Alan Boss, who first proposed the disk instability theory in 1997. During his ...
