A Race Against The Clock: Constraining The Timing Of Cometary Bombardment Relative To Earth’s Growth
Comets are considered a potential source of inner solar system volatiles, but the timing of this delivery relative to that of Earth’s accretion is still poorly understood.

Detectability of Planetesimal Impacts on Giant Exoplanets
The detectability of planetesimal impacts on imaged exoplanets can be measured using Jupiter during the 1994 comet Shoemaker-Levy 9 events as a proxy. By integrating the whole planet flux with […]
