| Popis: | Dust ejection efficiency from Phobos/Deimos controls dust abundance of Martian dust torus. Martian oblateness effect together with solar radiation pressure enhances abundance of particles with radius 20-200 micrometer of Phobos' dust torus. This is compatible with typical size of Phobos' surface regolith. Ejecta from torus particles-satellite collision should be the most important dust source. Surface erosion rate of satellites should constrain the dust ejection efficiency at collision. 資料番号: AA0063352059 |
