We review the major impact‐associated mechanisms proposed to cause extinctions at the
Cretaceous‐Tertiary geological boundary. We then discuss how the proposed extinction …

Shock waves and the associated phenomena generated by strongly ablating meteoroids
with sizes greater than a few millimeters in the lower transitional flow regime of the Earth's …

The asteroid impact near the Russian city of Chelyabinsk on 15 February 2013 was the
largest airburst on Earth since the 1908 Tunguska event, causing a natural disaster in an …

We perform modeling investigations to aid in understanding the atmospheres and
composition of small planets of∼ 2–4 Earth radii, which are now known to be common in our …

Hubble Space Telescope (HST) images reveal major atmospheric changes created by the
collision of comet Shoemaker-Levy 9 with Jupiter. Plumes rose to 3000 kilometers with …

The Deep Impact probe collided with 9P Tempel 1 at an angle of about 30° from the
horizontal. This impact angle produced an evolving ejecta flow field very similar to much …

A two-dimensional numerical model with radiation and ablation is developed for the study of
the impact of rather large (several meters or several tens of meters) meteoroids. This model …

Computational models for the July, 1994 collision of comet Shoemaker‐Levy 9 with Jupiter
have provided a framework for interpreting the observational data. Imaging, photometry, and …

The Tunguska event remained enigmatic for almost 100 years until the collision of Comet
Shoemaker-Levy 9 with Jupiter in 1994 helped to resolve this enigma and allowed us to …

Two months after the discovery of comet Shoemaker-Levy 9 came the astonishing
announcement that the comet would impact Jupiter in July 1994. Computing the orbital …
