From Interstellar Dust to Comets: Distributed Co in Comet Halleyate cores are the heating agent by solar radiation in fluffy aggregates of interstellar core-mantle particles, imposes a minimum dust porosity of 0.975 ≤ . ≤ 0.99. Such porosities are consistent with those required to account for the silicate and organic spectral emission by Comet Halley dust and imply comet nucleus densities of . < 0.3 ...Expressly 发表于 2025-3-27 17:32:47
Trapping of Gases in Water Ice and Consequences to Comets and the Atmospheres of the Inner Planets contribution of cometary impacts to the volatile inventory on the inner planets. The ejection of ice grains during massive gas release could hint to the mechanism of crater formation on the surface of comets and to the renewal of their activity at large distances post perihelion, as was observed for comet P/Halley.群岛 发表于 2025-3-27 21:24:20
Composition and Physical Properties of Comets margin) by refractories, very porous and fragile (though monolithic rather than of rubble-pile structure), and generally quite homogeneous except for dust mantling and the effects of radial migration of volatiles in the interiors.暗讽 发表于 2025-3-28 00:52:41
