The dynamical evolution of classical Kuiper belt objects (CKBOs) is divided into two parts, according to the secular theory of test particle orbits. The first part is a forced oscillation driven by the planets, while the second part is a free oscillation whose amplitude is determined by the initial orbit of the test particle. We extract the free orbital inclinations and free orbital eccentricities from the osculating elements of 125 known CKBOs. The free inclinations of 32 CKBOs strongly…

A collisional family of icy objects in the Kuiper belt
TLDR
The discovery of a family of Kuiper belt objects with surface properties and orbits that are nearly identical to those of 2003 EL61, which appears to be fragments of the ejected ice mantle of2003 EL61.
IDENTIFYING COLLISIONAL FAMILIES IN THE KUIPER BELT
The identification and characterization of numerous collisional families—clusters of bodies with a common collisional origin—in the asteroid belt has added greatly to the understanding of asteroid
The dynamical evolution of dwarf planet (136108) Haumea’s collisional family: general properties and implications for the trans-Neptunian belt
Recently, the first collisional family was identified in the trans-Neptunian belt (otherwise known as the Edgeworth-Kuiper belt), providing direct evidence of the importance of collisions between
Dynamically correlated minor bodies in the outer Solar system
The organization of the orbits of most minor bodies in the Solar system seems to follow random patterns, the result of billions of years of chaotic dynamical evolution. Much as heterogeneous orbital
Resonant and Secular Families of the Kuiper Belt
We review ongoing efforts to identify occupants of mean-motion resonances(MMRs) and collisional families in the Edgeworth–Kuiper belt. Directintegrations of trajectories of Kuiper belt objects (KBOs)
JUMPING NEPTUNE CAN EXPLAIN THE KUIPER BELT KERNEL
The Kuiper Belt is a population of icy bodies beyond the orbit of Neptune. A particularly puzzling and up-to-now unexplained feature of the Kuiper Belt is the so-called “kernel,” a concentration of
Trans-Neptunian Objects as Natural Probes to the Unknown Solar System
Trans-Neptunian objects (TNOs) are icy/rocky bodies that move beyond the orbit of Neptune in a region known as the trans-Neptunian belt (or Edgeworth-Kuiper belt). In contrast to the predictions of

The Deep Ecliptic Survey (DES)—a search optimized for the discovery of Kuiper belt objects (KBOs) with the Blanco and Mayall 4 m telescopes at the Cerro Tololo Inter-American Observatory and Kitt
Dynamic evolution of pairs of trans-Neptunian objects: the case of binary and single objects in pair
We performed a search for pairs of trans-Neptunian objects in close orbits with semi-major axes of more than 30 AU. Distances in the space of Keplerian orbits were estimated using the Kholshevnikov
Peculiar orbits and asymmetries in extreme trans-Neptunian space
It is still an open question how the Solar system is structured beyond 100 au from the Sun. Our understanding of this vast region remains very limited and only recently we have become aware of the

Dynamical Spreading of Asteroid Families by the Yarkovsky Effect
TLDR
Assuming that D ≲ 20 kilometer family members, since their formation, have undergone semimajor axis drift by the thermal force called the Yarkovsky effect helps explain why families are sharply bounded by nearby Kirkwood gaps, why some families have asymmetric shapes, and the curious presence of family members on short-lived orbits.
