In this work, we report the detection of seven Neptune Trojans (NTs) in the Pan-STARRS 1 (PS1) survey. Five of these are new discoveries, consisting of four L4 Trojans and one L5 Trojan. Our orbital simulations show that the L5 Trojan stably librates for only several million years. This suggests that the L5 Trojan must be of recent capture origin. On the other hand, all four new L4 Trojans stably occupy the 1:1 resonance with Neptune for more than 1 Gyr. They can, therefore, be of primordial… 
Neptune Trojans: a Revisit and a New Membertwo
A Dwarf Planet Class Object in the 21:5 Resonance with Neptune
We report the discovery of an Hr = 3.4 ± 0.1 dwarf planet candidate by the Pan-STARRS Outer Solar System Survey. 2010 JO179 is red with (g − r) = 0.88 ± 0.21, roughly round, and slowly rotating, with
Asteroids in the High Cadence Transient Survey
We report on the serendipitous observations of solar system objects imaged during the High cadence Transient Survey 2014 observation campaign. Data from this high-cadence wide-field survey was
Discovery and Dynamical Analysis of an Extreme Trans-Neptunian Object with a High Orbital Inclination
We report the discovery and dynamical analysis of 2015 BP519, an extreme trans-Neptunian object (TNO) detected by the Dark Energy Survey at a heliocentric distance of 55 au, perihelion of ∼36 au, and
Evaluating the Dynamical Stability of Outer Solar System Objects in the Presence of Planet Nine
We evaluate the dynamical stability of a selection of outer solar system objects in the presence of the proposed new solar system member Planet Nine. We use a Monte Carlo suite of numerical N-body
A dearth of small members in the Haumea family revealed by OSSOS
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 to constrain its
Searching for Moving Objects in HSC-SSP: Pipeline and Preliminary Results
TLDR
A new pipeline for detecting moving objects (specifically TNOs) in a non-dedicated survey is introduced using the HSC-SSP catalogs are re-arranged into the HEALPix architecture and the stationary detections and false positive are removed to produce a list of moving object candidates.

THE SIZE DISTRIBUTION OF THE NEPTUNE TROJANS AND THE MISSING INTERMEDIATE-SIZED PLANETESIMALS
We present an ultra-deep survey for Neptune Trojans using the Subaru 8.2 m and Magellan 6.5 m telescopes. The survey reached a 50% detection efficiency in the R band at mR = 25.7 mag and covered 49
How Long-Lived Are the Hypothetical Trojan Populations of Saturn, Uranus, and Neptune?
We investigate the possibility that fractions of the primordial populations at the triangular Lagrangian points of Saturn, Uranus, and Neptune have survived to the present and form (as yet
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 in
2008 LC18: A potentially unstable Neptune Trojan
The recent discovery of the first Neptune Trojan at the planet's trailing (L5) Lagrange point, 2008 LC18, offers an opportunity to confirm the formation mechanism of a member of this important tracer

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.
2004 KV18: a visitor from the scattered disc to the Neptune Trojan population
We have performed a detailed dynamical study of the recently identified Neptunian Trojan 2004 KV18, only the second object to be discovered librating around Neptune's trailing Lagrange point, L5. We
