Neptune Trojans and Plutinos are two subpopulations of trans-Neptunian objects located in the 1:1 and the 3:2 mean motion resonances with Neptune, respectively, and therefore protected from close encounters with the planet. However, the orbits of these two kinds of objects may cross very often, allowing a higher collisional rate between them than with other kinds of trans-Neptunian objects, and a consequent size distribution modification of the two subpopulations. Observational colors and… Expand
Reprint of "Evidence for color dichotomy in the primordial Neptunian Trojan population"
Abstract In the current model of early Solar System evolution, the stable members of the Jovian and Neptunian Trojan populations were captured into resonance from the leftover reservoir ofExpand

Origin and dynamical evolution of Neptune Trojans – II. Long-term evolution
Following our earlier work studying the formation of the Neptunian Trojan population during the planet's migration, we present results examining the eventual fate of the Trojan clouds produced inExpand
OSSOS: The eccentricity and inclination distributions of the stable neptunian Trojans
Abstract The minor planets on orbits that are dynamically stable in Neptune’s 1:1 resonance on Gyr timescales were likely em:laced by Neptune’s outward migration. We explore the intrinsic librationExpand
USING KUIPER BELT BINARIES TO CONSTRAIN NEPTUNE'S MIGRATION HISTORY
Approximately 10‐20% of all Kuiper belt objects (KBOs) occupy mean-motion resonances with Neptune. This dynamical configuration likely resulted from resonance capture as Neptune migrated outwardExpand
Search for L5 Earth Trojans with DECam.
TLDR
This work places the most stringent constraints to date on the population of Earth Trojans using the DECam instrument on the Blanco Telescope at CTIO, consistent with previous L4 Earth Trojan constraints and significantly improve L5 constraints. Expand
2007 TY430: A COLD CLASSICAL KUIPER BELT TYPE BINARY IN THE PLUTINO POPULATION
Kuiper Belt object 2007 TY430 is the first wide, equal-sized, binary known in the 3:2 mean motion resonance with Neptune. The two components have a maximum separation of about 1 arcsec and are onExpand
SLOAN DIGITAL SKY SURVEY OBSERVATIONS OF KUIPER BELT OBJECTS: COLORS AND VARIABILITY
Colors of trans-Neptunian objects (TNOs) are used to study the evolutionary processes of bodies in the outskirts of the solar system and to test theories regarding their origin. Here I describe aExpand
Orbital analysis of small bodies in co-orbital motion with Jupiter through the torus structure
In this paper, based on the torus structure, we investigate the orbital characteristics of Jupiter Trojans and Jupiter-family comets (JFCs) in co-orbital motion with Jupiter. The motivation of thisExpand
Expanded solar-system limits on violations of the equivalence principle
Most attempts to unify general relativity with the standard model of particle physics predict violations of the equivalence principle associated in some way with the composition of the test masses.Expand

A Thick Cloud of Neptune Trojans and Their Colors
TLDR
The discovery of a high-inclination Neptune Trojan, 2005 TN53 demonstrates that the Neptune Trojan population occupies a thick disk, which is indicative of “freeze-in” capture instead of in situ or collisional formation. Expand
