A sound nebula. The origin of the Solar System in the field of a standing sound wave

According to the planet origin concept proposed in this paper the protosun center explodes resulting in a shock wave running through the pre-solar nebula that then returns to the center and generates a new explosion and a new wave. Recurrent explosions in the pre-solar nebula result in a spherical standing sound wave with its antinodes concentrating dust. Dust then forms rotating rings that transform into planets. The extremely small Sun’s angular momentum (0.5%) and the tilt of the equatorial plane (7°) are caused by the asymmetry of the first most powerful explosion. Distinction between internal and external planets is explained by the migration of the solid matter. The Oort cloud is explained by the division of the pre-solar nebula into a spherical internal nebula and a expanding spherical shell of gas during the transit of the first explosion shock wave. The proposed concept can explain the origin and evolution of exoplanetary systems as well as help in searching for new planets.
