The Contribution of Dwarf Planets to the Origin of Jupiter Family Comets
Marco A. Muñoz-Gutiérrez, Antonio Peimbert, Bárbara Pichardo +2
We explore the long-term evolution of a bias-free orbital representation of the cometary nuclei (with diameters above 2 km) of the Kuiper belt, using the so-called L7 synthetic mod…
The Properties of Planetesimal Collisions under Jupiter's Perturbation and the Application to Chondrule Formation via Impact Jetting
Shoichi Oshino, Yasuhiro Hasegawa, Shigeru Wakita +1
Understanding chondrule formation provides invaluable clues about the origin of the solar system. Recent studies suggest that planetesimal collisions and the resulting impact melts…
A Dearth of Small Members in the Haumea Family Revealed by the OSSOS Survey
Rosemary E. Pike, Benjamin C. N. Proudfoot, Darin Ragozzine +8
While collisional families are common in the asteroid belt, only one is known in the Kuiper belt, linked to the dwarf planet Haumea. The characterization of Haumea's family helps t…
OSSOS IXX: Testing Early Solar System Dynamical Models using OSSOS Centaur Detections
David Nesvorny, David Vokrouhlicky, Alan S. Stern +9
We use published models of the early Solar System evolution with a slow, long-range and grainy migration of Neptune to predict the orbital element distributions and the number of m…
The REASONS Survey: Resolved Millimeter Observations of a Large Debris Disk Around the Nearby F Star HD 170773
Aldo G. Sepulveda, Luca Matra, Grant M. Kennedy +15
Debris disks are extrasolar analogs to our own Kuiper Belt and they are detected around at least 17% of nearby Sun-like stars. The morphology and dynamics of a disk encode informat…
The HD 181433 Planetary System: Dynamics and a New Orbital Solution
Jonathan Horner, Robert A Wittenmyer, Duncan J Wright +7
We present a detailed analysis of the orbital stability of the HD 181433 planetary system, finding it to exhibit strong dynamical instability across a wide range of orbital eccentr…
