from a "Google Scholar" search.Solar System Formation DeducedAspects of our Solar System’s formation are deduced from observations of the chemical nature of matter. Massive cores are indicative of terrestrial-planet-composition-similarity to enstatite chondrite meteorites, whose highly-reduced state of oxidation may be thermodynamically stable in solar matter only at elevated temperatures and pressures. Consistent with the formation of Earth as envisioned by Arnold Eucken, thermodynamic considerations lead to the deduction that the terrestrial planets formed by liquid-condensation, raining out from the central regions of hot, gaseous protoplanets. The mass of protoplanetary-Earth... is similar to the mass of Jupiter... Hans Suess and I demonstrated from thermodynamic considerations that the oxidized iron content of the silicates of ordinary chondrites is inconsistent with formation from solar matter, as purported by the “equilibrium condensation” model, and instead is indicative of their formation from a gas phase depleted in hydrogen by a factor of about 1000 relative to solar composition (Herndon & Suess 1977). Subsequently, I showed that oxygen depletion, relative to solar matter, was also required, otherwise essentially all of the elements would be observed combined with oxygen as they are in the hydrous C1 carbonaceous chondrites (Table 1). I also showed that if the mineral assemblage characteristic of ordinary chondrites could exist in equilibrium with a gas of solar composition, it is at most only at a single low temperature, if at all (Herndon 1978). Such a mineral assemblage, therefore, cannot legitimately be assumed to be a primary Solar System condensate. Instead, the ordinary chondrite meteorites appear to have formed from a mixture of two components, re-evaporated after separation from solar gases, one component being an oxidized primitive matter like C1 chondrites, the other being a partially differentiated planetary component from enstatite-chondrite-like matter (Herndon 2004b).

Can't quite understand how Herndon says the Jovian and terran dust lanes were equal in mass during the T Tauri birth phase. Jupiter today is 318 earth-masses. The TEDF theory easily explains how the proto-planets were graded/sorted as accretion vortices depending on radial distance, the gradients being gravity(drops by inverse square), thermal(by some log factor) and magnetic B dot field(drops by inverse CUBE). Thus mercury and venus are refractory-rich but have virtually no spin(counter-acting CW from coriolis effect of a contracting vortex vs CCW spin from B dot field)because the lenticular-flat proto-sun had to get RID of virtually all its original spin(into planetary orbital momentum)to become spherical. In the outer gas bags, yes, they swept up virtually all of the H2/He in their dust lanes because it was cooler but also look at the ecliptic AREAS of those accretion vortices-in-dust-lanes(vs proto-earth's).
