We reexamine the correlation between the colors and the inclinations of the Classical Kuiper Belt Objects (CKBOs) with an enlarged sample of optical measurements. The correlation is strong (ρ = −0.7) and highly significant (>8σ) in the range 0°–34°. Nonetheless, the optical colors are independent of inclination below ≈12°, showing no evidence of a break at the reported boundary between the so-called dynamically “hot” and “cold” populations near ≈5°. The commonly accepted parity between the…

COLORS OF INNER DISK CLASSICAL KUIPER BELT OBJECTS
We present new optical broadband colors, obtained with the Keck 1 and Vatican Advanced Technology telescopes, for six objects in the inner classical Kuiper Belt. Objects in the inner classical Kuiper
INCLINATION MIXING IN THE CLASSICAL KUIPER BELT
We investigate the long-term evolution of the inclinations of the known classical and resonant Kuiper Belt objects (KBOs). This is partially motivated by the observed bimodal inclination distribution

Col-OSSOS: Color and Inclination Are Correlated throughout the Kuiper Belt
Both physical and dynamical properties must be considered to constrain the origins of the dynamically excited distant solar system populations. We present high-precision (g–r) colors for 25 small (Hr
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 a
THE COLOR DIFFERENCES OF KUIPER BELT OBJECTS IN RESONANCE WITH NEPTUNE
The optical colors of 58 objects in mean motion resonance with Neptune were obtained. The various Neptune resonant populations were found to have significantly different surface color distributions.
THE COLORS OF EXTREME OUTER SOLAR SYSTEM OBJECTS
Extreme outer solar system objects have possible origins beyond the Kuiper Belt edge, high inclinations, very large semimajor axes, or large perihelion distances. Thirty-three such objects were
Light Curves and Rotational Properties of the Pristine Cold Classical Kuiper Belt Objects
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
The Rarity of Very Red Trans-Neptunian Objects in the Scattered Disk
We investigate the origins of the photometrically very red (VR) and less red (LR) trans-Neptunian objects (TNOs). We first reanalyze the data set of Marsset et al. and find that in addition to the

A Correlation between Inclination and Color in the Classical Kuiper Belt
We have measured broadband optical BVR photometry of 24 classical and scattered Kuiper belt objects (KBOs), approximately doubling the published sample of colors for these classes of objects. We find
Colors and Spectra of Kuiper Belt Objects
We present new measurements of the optical colors of Kuiper belt objects, principally from the Keck 10 m telescope. The measurements confirm the existence of a wide spread in the B-V, V-R, and R-I

Rotation rates of Kuiper-belt objects from their light curves
Very little is known about the physical properties of Kuiper-belt objects, due to their relatively small size and large distance from the Earth. For example, a Kuiper-belt object with a diameter of
Extremely red Kuiper-belt objects in near-circular orbits beyond 40  AU
TLDR
It is reported that all nine of the KBOs in this survey on near-circular (low-eccentricity) orbits with perihelion distances larger than 40 AU have extremely red surfaces, thereby connecting an observable property with a dynamical class.

We develop a general method for determining the unbiased inclination distribution of the Kuiper belt using only the inclination and latitude of discovery of known Kuiper belt objects (KBOs). These
