Ever since the very first photometric studies of Centaurs and Kuiper belt objects (KBOs) their visible color distribution has been controversial. This controversy has triggered to a prolific debate on the origin of the surface colors of these distant icy objects of the solar system. Two scenarios have been proposed to interpret and explain the large variability of colors, hence surface composition. Are the colors mainly primordial and directly related to the formation region, or are they the…

The Bimodal Color Distribution of Small Kuiper Belt Objects

We conducted a two-night photometric survey of small Kuiper Belt objects (KBOs) near opposition using the wide-field Hyper Suprime-Cam instrument on the 8.2 m Subaru Telescope. The survey covered

TWO COLOR POPULATIONS OF KUIPER BELT AND CENTAUR OBJECTS AND THE SMALLER ORBITAL INCLINATIONS OF RED CENTAUR OBJECTS

We present new optical colors for 28 Kuiper Belt objects (KBOs) and 35 Centaur objects measured with the 1.8 m Vatican Advanced Technology Telescope and the 4.3 m Discovery Channel Telescope. By

An Investigation on the Origin of Centaurs’ Color–Inclination Relation

Since its discovery, there has been a debate in the past few decades on the origin of the bimodal color distribution of Centaurs. Two theories have been proposed to explain this bimodal color

OSSOS XX: The Meaning of Kuiper Belt Colors

Observations show that 100 km class Kuiper Belt objects (KBOs) can be divided into (at least) two color groups, red (R; g − i < 1.2) and very red (VR; g − i > 1.2), reflecting a difference in their

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

A HYPOTHESIS FOR THE COLOR BIMODALITY OF JUPITER TROJANS

One of the most enigmatic and hitherto unexplained properties of Jupiter Trojans is their bimodal color distribution. This bimodality is indicative of two sub-populations within the Trojans, which

Reanalyzing the visible colors of Centaurs and KBOs: what is there and what we might be missing

Visible colors (BVRI) are a reasonable proxy for real spectra of Centaurs and Kuiper Belt Objects, which are rather linear in this range. Colors provide limited information but remain the best tool

Col-OSSOS: Compositional Homogeneity of Three Kuiper Belt Binaries

The surface characterization of Trans-Neptunian binaries (TNBs) is key to understanding the properties of the disk of planetesimals from which these objects formed. In the optical wavelengths, it has

THE DIFFERING MAGNITUDE DISTRIBUTIONS OF THE TWO JUPITER TROJAN COLOR POPULATIONS

The Jupiter Trojans are a significant population of minor bodies in the middle solar system that have garnered substantial interest in recent years. Several spectroscopic studies of these objects

ON A POSSIBLE SIZE/COLOR RELATIONSHIP IN THE KUIPER BELT

Color measurements and albedo distributions introduce non-intuitive observational biases in size–color relationships among Kuiper Belt Objects (KBOs) that cannot be disentangled without a well

Colors of Centaurs

Minor planets on outer planet-crossing orbits, called Centaur objects, are important members of the solar system in that they dynamically link Kuiper belt objects to Jupiter-family comets. In

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

The Color Distribution in the Edgeworth-Kuiper Belt

In 1997 we began the Meudon Multicolor Survey of Outer Solar System Objects with the aim of collecting a large and homogeneous set of color data for trans-Neptunian objects (TNOs) and Centaurs. Here

As a result of our continuing photometric survey, we report here optical colors for 36 Kuiper Belt objects, increasing our sample size to 91 objects. We find that certain dynamical classes of objects
