Meteorite Impacts, Craters and Multi-ring Basins
One of the principal new results of space exploration has been the demonstration that impact cratering was endemic throughout the solar system. Whether one is contemplating the cratered face of Mercury, the traces of the bombardment surviving on Venus or the Earth, the heavily cratered highland surface of the Moon or the southern hemisphere of Mars, the battered potato-like surfaces of Phobos a...
متن کاملCometary and Meteorite Swarm Impact on Planetary Surfaces
The velocity flow fields, energy partitioning, and ejecta distributions resulting from impact of porous (fragmented) icy cometary nuclei with silicate planetary surfaces at speeds from 5 to 45 km/s are different than those resulting from the impact of solid ice or silicate meteorites. The impact of ! g/cm 3 ice spheres onto an atmosphereless anorthosite planetary surface induces cratering flows...
متن کاملMorphology and Evolution of the Large Magellanic Cloud Planetary Nebulae1
The LMC is ideal for studying the coevolution of planetary nebulae (PNs) and their central stars in that the debilitating uncertainties of the Galactic PN distance scale and selection biases from attenuation by interstellar dust do not apply. We present images and analyze slitless spectra that were obtained in a survey of Large Magellanic Cloud PNs. These data on 29 targets were obtained with t...

متن کاملCombined Structural and Compositional Evolution of Planetary Rings Due to Micrometeoroid Impacts and Ballistic Transport
We introduce improved numerical techniques for simulating the structural and compositional evolution of planetary rings due to micrometeoroid bombardment and subsequent ballistic transport of impact ejecta. Our current, robust code is capable of modeling structural changes and pollution transport simultaneously over long times on both local and global scales. In this paper, we describe the meth...
