The effect of pre-impact spin on the Moon-forming collision
Sergio Ruiz-Bonilla, Vincent R. Eke, Jacob A. Kegerreis +2
We simulate the hypothesised collision between the proto-Earth and a Mars-sized impactor that created the Moon. Amongst the resulting debris disk in some impacts, we find a self-gr…
Atmospheric Erosion by Giant Impacts onto Terrestrial Planets: A Scaling Law for any Speed, Angle, Mass, and Density
Jacob A. Kegerreis, Vincent R. Eke, David C. Catling +3
We present a new scaling law to predict the loss of atmosphere from planetary collisions for any speed, angle, impactor mass, target mass, and body compositions, in the regime of g…
Atmospheric Erosion by Giant Impacts onto Terrestrial Planets
J. A. Kegerreis, V. R. Eke, R. J. Massey +1
We examine the mechanisms by which atmosphere can be eroded by giant impacts onto Earth-like planets with thin atmospheres, using 3D smoothed particle hydrodynamics simulations wit…
