Fire Under Fire: Proton Probabilities at Perihelion

This paper computes the probabilities that the near-Sun flyby mission, Fire, might be bombarded by high energy protons from solar-activity related proton acceleration lying beneath Fire’s perihelion altitude of three solar radii. Although the very largest interplanetary proton events are commonly believed to be caused by interplanetary shocks, this paper assumes the working hypothesis that ther...

On The Origin of Pluto , Charon , and the Pluto

Being small, binary, and in a highly unusual orbit, Pluto was long viewed as an enigma in the outer Solar System. Here we review the historical development of ideas concerning Pluto's origin and the origin of the Pluto-Charon Binary. We critically examine these theories in light of both recent advances about Pluto, and with regard to Pluto's broader context in the outer Solar System. Although P...
