Instead of collapsing directly to form a flat continuous disk, due to 'turbulent stress' the gas temporarily remains puffed up in a vast rotating spheroidal atmosphere around the protosolar core.
[2] Andrew Prentice was a member of the lecturing staff at Monash University, Clayton; he received a Vice-Chancellor's Award for Teaching Excellence in 2011.
In 2014 the ALMA radio telescope started observing the inner regions around young stars,[4] such as HL Tauri and AS 209,where planets were thought to be forming.
To the surprise of the astronomical community ALMA found that most of these stars are encircled by sets of concentric rings, similar to those described by Prentice in 1978,[6] rather than continuous disks.
Prentice has made a long list of controversial predictions about the nature of our Solar System in an attempt to demonstrate the validity of his Modern Laplacian Theory.
