Quantifying Jupiter's influence on the Earth's impact flux: Implications for planetary habitability
J. Horner, B. W. Jones
It has long been thought that the presence of a giant planet is a pre-requisite for the development of life on potentially habitable planets. Without Jupiter, it was argued, the Ea…
Jupiter - Friend or Foe? IV: The influence of orbital eccentricity and inclination
J. Horner, B. W. Jones
For many years, it was assumed that Jupiter prevented the Earth from being subject to a punishing impact regime that would greatly hinder the development of life. Here, we present…
Jupiter - friend or foe? III: the Oort cloud comets
J Horner, B W Jones, J Chambers
It has long been assumed that the planet Jupiter acts as a giant shield, significantly lowering the impact rate of small bodies on the Earth. However, until recently, very little w…
Origin and Dynamical Evolution of Neptune Trojans - I: Formation and Planetary Migration
P. S. Lykawka, J. Horner, B. W. Jones +1
We present the results of detailed dynamical simulations of the effect of the migration of the four giant planets on both the transport of pre-formed Neptune Trojans, and the captu…
