The Properties and Origin of Kuiper Belt Object Arrokoth's Large Mounds

The Planetary Science Journal, 2023
We report on a study of the mounds that dominate the appearance of Kuiper Belt Object (486958) Arrokoth's larger lobe, named Wenu. We compare the geological context of these mounds and measure and intercompare their shapes, sizes/orientations ...

Machine Learning Classification of Kuiper Belt Populations. [PDF]

Mon Not R Astron Soc, 2020
In the outer Solar system, the Kuiper belt contains dynamical subpopulations sculpted by a combination of planet formation and migration and gravitational perturbations from the present-day giant planet configuration.

Light Curves and Rotational Properties of the Pristine Cold Classical Kuiper Belt Objects [PDF]

The Astronomical Journal, 2019
Abstract We present a survey of the rotational and physical properties of the dynamically low inclination Cold Classical (CC) trans-Neptunian objects (TNOs). The CCs are primordial planetesimals and contain information about our solar system and planet formation over the first 100 million years after the Sun’s formation.

Long-Term Dynamics and the Orbital Inclinations of the Classical Kuiper Belt Objects [PDF]

The Astronomical Journal, 2002
We numerically integrated the orbits of 1458 particles in the region of the classical Kuiper Belt (41 AU < a < 47 AU) to explore the role of dynamical instabilities in sculpting the inclination distribution of the classical Kuiper Belt Objects (KBOs). We find that the selective removal of low-inclination objects by overlapping secular resonances (

Close Trans-Neptunian Object Passages as a Driver of the Origin and Evolution of Ultrawide Kuiper Belt Binaries

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

CHIMERA Occultation Constraints on the Abundance of Kilometer-scale Kuiper Belt Objects

The Astronomical Journal, 2023
Occultations provide indirect sensitivity to the number density of small Kuiper Belt objects (KBOs) too faint to directly detect telescopically. We present results from the Caltech HI-speed Multicolor camERA (CHIMERA) survey with the Palomar Hale ...

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 ...

Unbiased Inclination Distributions for Objects in the Kuiper Belt [PDF]

, 2010
Using data from the Deep Ecliptic Survey (DES), we investigate the inclination distributions of objects in the Kuiper Belt. We present a derivation for observational bias removal and use this procedure to generate unbiased inclination distributions for ...

Col-OSSOS: Evidence for a Compositional Gradient Inherited from the Protoplanetary Disk?

The Planetary Science Journal, 2023
In the present-day Kuiper Belt, the number of compositional classes and the orbital distributions of these classes hold important cosmogonic implications for the solar system.
