Trapping of Dust by Coherent Vortices in the Solar Nebula
We develop the idea proposed by Barge & Sommeria (1995) and Tanga et al. (1996) that large-scale vortices present in the solar nebula can concentrate dust particles and facilitate the formation of planetesimals and planets. We introduce an exact vortex solution of the incompressible 2D Euler equation and study the motion of dust particles in that vortex. In particular, we derive analytical expr...
متن کاملOn the Growth of Dust Particles in a Non-Uniform Solar Nebula
It has recently been shown that the combined effect of gas drag and pressure gradients causes solid objects to rapidly migrate toward the location of maximum pressure in a gaseous nebula [1, 2]. Such rapid migrations result in the accumulation of objects in the vicinity of local pressure enhancement and may increase the rates of their collisions and coagulations. In a disk with a mixture of gas...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولRapid Growth of Dust Particles in the Vicinity of Local Gas Density Enhancements in a Solar Nebula
The results of a numerical study of the growth of solid particles, ranging from 1 micron to 1 millimeter in size, in the vicinity of an azimuthally symmetric density enhancement of a protostellar disk are presented. It is shown that the combined effect of gas drag and pressure gradients, which causes solid objects to rapidly migrate toward the location of the local maximum density, can also enh...
