Sun Close-Encounter Model of Long-Period Comet and Meteoroid Orbit Stochastic Evolution
Stuart Pilorz, Peter Jenniskens
The dynamical evolution of long-period comets (LPCs) and their meteoroid streams is usually described with the Sun as the primary body, but over most of their orbits the Solar Syst…

How Meteor Showers Can Guide the Search for Long Period Comets
Samantha Hemmelgarn, Nicholas Moskovitz, Stuart Pilorz +1
With orbital periods longer than 200 years, most long-period comets (LPCs) remain undiscovered until they are in-bound towards perihelion. The comets that pass close to Earth's orb…

Properties of outer solar system pebbles during planetesimal formation from meteor observations
Peter Jenniskens, Paul R. Estrada, Stuart Pilorz +42
In the late stages of accretion leading up to the formation of planetesimals, particles grew to pebbles the size of 1-mm to tens of cm. That is the same size range that dominates t…
