Sun a b 摘要: Compositional models of the Earth are critically dependent on three main sources of information: the seismic profile of the Earth and its interpretation, comparisons between primitive meteorites and the solar nebula composition, and chemical and petrological models of peridotite-basalt ...
Comets seem to be composed of matter, which is supposed to have the same molecular composition as protosolar nebula. Although there are no unbiased evidence that cometary nuclei retain the molecular composition inherited from the protosolar cloud, the observed properties of comets indicate that ...

Protostellar disks around young stars similar to the protosun provide a way of investigating the evolution of disks similar to the solar nebula while they are in the process of evolving to form their own solar systems. In this way we can learn about the physical and chemical conditions under...
Observations of comets and asteroids show that the solar nebula that spawned our planetary system was rich in water and organic molecules. Bombardment brought these organics to the young Earth's surface. Unlike asteroids, comets preserve a nearly pristine record of the solar nebula composition. The...
The determination of the composition of materials that make up comets is essential in trying to understand the origin of these primitive objects. The ices especially could be made in several different astrophysical settings including the solar nebula, protosatellite nebulae of the giant planets, and ...
The condensation with partial isolation (CWPI) model of condensation in the solar nebula MICHAIL I. PETAEV,JOHN A. WOOD - 《Meteoritics & Planetary Science》 - 1998 - 被引量: 223 Fourteen months of on-line measurements of the non-refractory submicron aerosol at the Jungfraujoch (3580 m a...
The Earth began to gravitationally accumulate out-of-solar nebula debris surrounding the newly ignited Sun, approximately 4.5 billion years ago. The process of gravitational accumulation is a snowball effect: clumping materials form a larger body which increases it's gravity which causes it to subsequ...
