A model for the formation of Kuiper belts and Oort cloudsI have developed a rather detailed quantum model for the formation of planets based on quantum coherence in astrophysical scales (see this). In this posting the extension of this model to the formation of the Kuiper belt and Oort cloud is discussed. The former planet Pluto (see this) is the largest object in the Kuiper belt, which has a torus-like shape. The radius of Pluto is 1,191 km to be compared with Λgr= 3,000 and to the radius 2,439 km of Mercury. The assumption that Pluto is a planet of solar origin requires β0 → 3β0 for the Pluto-Sun pair at the time when Pluto originated if β0 has remained unchanged during its evolution. This does not conform with the proposed model. Could the Kuiper belt (see this), which is composed of mini-planets be analogous to a planetary ring, and be the oldest structure emanating from the Sun by the proposed mechanism? The total mass of Kuiper belt is recently about 10 per cent of the mass of Earth but there are reasons to believe that the original material has been 7 to 10 Earth masses so that Kuiper belt could be perhaps seen as a failed Jupiter sized giant planet for which the transformation of dark matter to ordinary matter did not lead to a single planet but to a large number of smaller objects. The standard view of the formation of astrophysical structures is very different from the TGD view (see this and earlier blog postings) and the standard model should have anomalies if the TGD view is nearer to truth. One example of such anomaly is described in the article "A dense ring of the trans-Neptunian object Quaoar outside its Roche limit" by Morgado et al (see this and this). The miniplanet known as Quaoar is an object half of the size of Pluto. The radius of the ring is 7 times the radius of Quaoar. The Roche limit is however 2.5 radii. Roche limit follows involved the assumption that the satellite is held together only by gravitational forces. The gravitational tidal forces pull apart a satellite rotating too near to a planet so that it forms a ring. Therefore the formation of stable satellites is not possible within Roche radius. Conversely, a pre-existing ring can eventually condense to a satellite if its radius is larger than the Roche limit. Also Saturn has two rings, which violate the Roche limit (see ). The E ring of Saturn, which - unlike smaller rings - consists of micron and submicron sized particles, violates the Roche limit. The particles of E ring to accumulate to Moons that orbit with the ring. Also the Phoebe ring associated with Saturn's moon Phoebe violates the Roche limit. Could the TGD view explain the violations of the Roche limit?
