Impact Craters in South America
(Springer, 2015)
A complete and updated catalogue of impact craters and structures in South America from 2014 is presented here. Approximately eighty proven, suspected and disproven structures have been identified by several sources in ...
Meteorite impact craters and ejecta in South America: a brief review
(União da Geomorfologia Brasileira, 2011-09)
The first catalogue of impact craters sites in South America is presented here. Proximately thirty proven, suspected and disproven structures have been identified by several sources in this continent until now. But everyone ...
Impact on porous targets: Penetration, crater formation, target compaction, and ejection
(American Physical Society, 2012-12)
Using a granular-mechanics code, we study the impact of a sphere into a porous adhesive granular target, consisting of monodisperse silica grains. The model includes elastic repulsive, adhesive, and dissipative forces, as ...
Penetration scaling in atomistic simulations of hypervelocity impact
(Elsevier, 2010-11)
We present atomistic molecular dynamics simulations of the impact of copper nano particles at 5 km s 1 on copper films ranging in thickness from from 0.5 to 4 times the projectile diameter. We access both penetration and ...
The production of craters on the mid-sized saturnian satelites by Centaur objects
(Edp Sciences, 2013-05)
Context. The Saturnian satellite system has been observed in detail by the Cassini-Huygens mission. These satellites present different surface features, including impact craters caused by small objects probably coming from ...
Catastrophic bolide impacts on the Earth: Some estimates
(American Association of Physics Teachers, 2006-09)
We analyze the impact of large high velocity bodies on the surface of the Earth and obtain estimates of the size of the crater. We show that the atmosphere does not stop large bolides and their mass loss and heating during ...
