The Kuiper Belt [PDF]

Symposium - International Astronomical Union, 1994
The existence of a belt of comets in the outer solar system (the “Kuiper belt”) has been postulated for a variety of reasons, including the need for a source for the short-period comets. The existence of the belt seems supported by the discoveries of the trans-Neptunian objects 1992 QB1, 1993 FW, 1993 RO, 1993 RP, 1993 SB, and 1993 SC. If these objects

WATER ICE IN THE KUIPER BELT [PDF]

The Astronomical Journal, 2012
We examine a large collection of low resolution near-infrared spectra of Kuiper belt objects and centaurs in an attempt to understand the presence of water ice in the Kuiper belt. We find that water ice on the surface of these objects occurs in three separate manners: (1) Haumea family members uniquely show surfaces of nearly pure water ice, presumably

Formation of Kuiper Belt Binaries [PDF]

The Astrophysical Journal, 2008
The discovery that a substantial fraction of Kuiper Belt objects (KBOs) exists in binaries with wide separations and roughly equal masses, has motivated a variety of new theories explaining their formation. Goldreich et al. (2002) proposed two formation scenarios: In the first, a transient binary is formed, which becomes bound with the aid of dynamical

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 ...

The Hot Main Kuiper Belt Size Distribution from OSSOS

The Astrophysical Journal Letters, 2023
Using the absolute detection calibration and abundant detections of the Outer Solar System Origins Survey project, we provide population measurements for the main Kuiper Belt.

Satellites of the Largest Kuiper Belt Objects [PDF]

The Astrophysical Journal, 2006
We have searched the four brightest objects in the Kuiper belt for the presence of satellites using the newly commissioned Keck Observatory Laser Guide Star Adaptive Optics system. Satellites are seen around three of the four objects: Pluto (whose satellite Charon is well-known), 2003 EL61, and 2003 UB313. The object 2005 FY9, the brightest Kuiper belt

Great Expectations: Plans and Predictions for New Horizons Encounter With Kuiper Belt Object 2014 MU69 (“Ultima Thule”)

Geophysical Research Letters, 2018
The New Horizons encounter with the cold classical Kuiper Belt object 2014 MU69 (informally named “Ultima Thule,” hereafter Ultima) on 1 January 2019 will be the first time a spacecraft has ever closely observed one of the free‐orbiting small denizens of

Hiding Dust around ϵ Eridani

The Astronomical Journal, 2023
With a Jupiter-like exoplanet and a debris disk with both asteroid and Kuiper Belt analogs, ϵ Eridani has a fascinating resemblance to our expectations for a young solar system.

Atmospheres and surfaces of small bodies and dwarf planets in the Kuiper Belt

EPJ Web of Conferences, 2010
Kuiper Belt Objects (KBOs) are icy relics orbiting the sun beyond Neptune left over from the planetary accretion disk. These bodies act as unique tracers of the chemical, thermal, and dynamical history of our solar system.

On nature of evolution of short-period comets. On the question of short-period comets evolution

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
The main hypothesis of short-period comets evolution are considered. Basing on the performed researches we conclude that the main sources of short-period comets are: main asteroid belt, relict asteroid belts between giant planets and the Kuiper belt.
