solar system are also discussed: in the inner planetary region, contributing to the formation of the planetary atmospheres and water reservoirs; in the asteroid and Kuiper belts, sculpting their primordial structures, and in the outer edge of the solar system, building up the Oort cloud of ...
Accretion processes in protoplanetary disks produce a diversity of small bodies that played a crucial role in multiple reshuffling events throughout the solar system and in both early and late accretion of planets. Application of thermo-chronometers to meteorites provides precise dating of the formation...
Solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular cr
5. The analysis model for the growth of film and ice was established and the influence of airflow parameters on the characteristics and rate of icing accretion was analyzed. 研究表明,在飞机结冰过程中,冰层生长速率及不同冰型的形成不但受来流参数的影响,而且与固、液相区的内部传热特性相关,因而考虑...
Abstract. An attempt has been made to model the helium accre-tion disc with parameters expected for AM CVn type systems. In the spectrum of such a system we expect to see signatures of all its parts: the central white dwarf, the degenerate secondary, the disc and the wind. Spectral ...

Core accretion theory lacks an explanation for the formation of the gas giants in the outer solar system due to the amount of time the process takes. In contrast, the pebble accretion model falls short of explaining the formation of the terrestrial planets due to a lack of building material ...
Abstract Earth grew through collisions with Moon-sized to Mars-sized planetary embryos from the inner Solar System, but it also accreted material from greater heliocentric distances1,2, including carbonaceous chondrite-like bodies, the likely source of Earth’s water and highly volatile species3,4....
