Says Boscoli, 'If this mass of gas . . . would begin to rotate upon itself, it would necessarily assume a progressively flatter ellipsoidal form as its rotational velocity increased. And . . the Ranque effect would begin to be exerted, therefore producing a cooling at the centre and a heating of the periphery of the ellipsoid.'


 

Reading that made my head hurt.

'...If this mass of gas... would begin to rotate upon itself, it would necessarily assume a progressively flatter ellipsoidal form as its rotational velocity increased. And... the Ranque effect would begin to be exerted, therefore producing a cooling at the centre and a heating of the periphery of the ellipsoid.'

Let me help you sort this out. Here is a recent telephoto taken at Mt. Palomar tentatively identifying an accumulating gas mass thought to be in a very primitive stage and just beginning to show the Ranque effect...
