Modified Newtonian Dynamics as an Alternative to the Planet Nine Hypothesis
The Astronomical Journal, 2023 A new class of Kuiper Belt objects (KBOs) that lie beyond Neptune with semimajor axes greater than 250 astronomical units show orbital anomalies that have been interpreted as evidence for an undiscovered ninth planet.

The Astronomical Journal, 2022 Within the dynamically cold low-inclination portion of the Classical Kuiper Belt, there exists a population of weakly bound binary systems with a number of unusual properties, most notable of which is their extremely wide orbital separations—beyond 7% of

Detection of methane on Kuiper Belt Object (50000) Quaoar [PDF]
, 2006 The near-infrared spectrum of (50000) Quaoar obtained at the Keck Observatory shows distinct absorption features of crystalline water ice, solid methane and ethane, and possibly other higher order hydrocarbons. Quaoar is only the fifth Kuiper belt object

The Kuiper Belt Luminosity Function from m(R)=21 to 26 [PDF]
, 2008 We have performed an ecliptic imaging survey of the Kuiper belt with our deepest and widest field achieving a limiting flux of m(g') = 26.4, with a sky coverage of 3.0 square-degrees.

Destruction of Binary Minor Planets During Neptune Scattering
, 2010 The existence of extremely wide binaries in the low-inclination component of the Kuiper Belt provides a unique handle on the dynamical history of this population. Some popular frameworks of the formation of the Kuiper Belt suggest that planetesimals were

Earth and Planetary Physics, 2022 A first-order question in the studies of the Solar System is how its outer zone known as the Kuiper belt was created and evolved. Two end-member models, involving coagulation vs. streaming instability, make different predictions—testable by the cratering

Neptune's Migration into a Stirred-Up Kuiper Belt: A Detailed Comparison of Simulations to Observations [PDF]
, 2005 Nbody simulations are used to examine the consequences of Neptune's outward migration into the Kuiper Belt, with the simulated endstates being compared rigorously and quantitatively to the observations. These simulations confirm the findings of Chiang et

The Trojan-like Colors of Low-perihelion Kuiper Belt Objects
The Planetary Science JournalAn important testable prediction of dynamical instability models for the early evolution of the solar system is that Jupiter Trojans share a source population with the Kuiper Belt.

Col-OSSOS: The Two Types of Kuiper Belt Surfaces
The Planetary Science Journal, 2023 The Colors of the Outer Solar System Origins Survey (Col-OSSOS) has gathered a high-quality, near-simultaneous, and brightness-complete sample of ( g − r ) and ( r − J ) colors for 102 Kuiper Belt objects (KBOs) with ( u − g ) and ( r − z ) gathered for ...
