Abstract

Prentice (1978a, b), in his modern Laplacian theory of the origin of the solar system, has established a scenario in which he finds the ratio of the orbital radii of successively disposed gaseous rings to be a constant ≃1.69. In an attempt to understand this law in an alternative way, Rawal (1984a) assumes that during the collapse of the solar nebula the halts at various radii are brought about by the supersonic turbulent convection and arrives at the relation of the formRp=Rap, whereR is the radius of the present Sun anda=1.422, is referred to, here, as the ‘Roche’ constant. Kepler's third law assumes the form:Tp=T0(a3/2) p ,T0 being the rotational period of the Sun at the time it attained its present radius.R p satisfy Laplace's resonance relation without any exception. The present paper investigates inter-relations among the concepts of supersonic turbulent convection, rotational instability, and Roche limit.
