The Solar System Beyond The Planets

  title={The Solar System Beyond The Planets},
  author={Audrey C. Delsanti and David C. Jewitt},
The Kuiper belt contains a vast number of objects in a flattened, ring-like volume beyond the orbit of Neptune. These objects are collisionally processed relics from the accretion disk of the Sun and, as such, they can reveal much about early conditions in the Solar system. At the cryogenic temperatures prevailing beyond Neptune, volatile ices have been able to survive since the formation epoch 4.5 Gyr ago. The Kuiper belt is the source of the Centaurs and the Jupiter-family comets. It is also… 
Investigation of the asteroid–neutron star collision model for the repeating fast radio bursts
The origin of fast radio bursts (FRBs) is still a mystery. One model proposed to interpret the only known repeating object, FRB 121102, is that the radio emission is generated from asteroids
Polluting white dwarfs with perturbed exo-comets
We present a model to account for the observed debris disks around young white dwarfs and the presence of metal-lines in their spectra. Stellar evolution models predict that the mass-loss on the AGB
A coupling of the origin of asteroid belt, planetary ring, and comet
Observations show that there are an asteroid belt, four giant planetary ring systems, and countless comets in the solar system. Various scenarios in the past had been presented to account for their
Trans-Neptunian objects (TNOs) are remnants of a collisionally and dynamically evolved planetesimal disk in the outer solar system. This complex structure, known as the trans-Neptunian belt (or
Mass of the Kuiper belt
The Kuiper belt includes tens of thousand of large bodies and millions of smaller objects. The main part of the belt objects is located in the annular zone between 39.4 and 47.8 au from the Sun; the
Origin and Evolution of the Cometary Reservoirs
Comets have three known reservoirs: the roughly spherical Oort Cloud (for long-period comets), the flattened Kuiper Belt (for ecliptic comets), and, surprisingly, the asteroid belt (for main-belt
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 Edgeworth-Kuiper debris disk
The Edgeworth-Kuiper belt (EKB) and its presumed dusty debris is a natural reference for extrsolar debris disks. We re-analyze the current database of known transneptunian objects (TNOs) and employ a
The population of centaurs in the Solar System
Context. Centaurs are objects with perihelia beyond the orbit of Jupiter and semi-major axes inside the orbit of Neptune. They show both cometary and asteroid characteristics, have been observed to


The binary Kuiper-belt object 1998 WW31
It is reported that the Kuiper-belt object 1998 WW31 is binary with a highly eccentric orbit (eccentricity e ≈ 0.8) and a long period (about 570 days), very different from the Pluto/Charon system, which was hitherto the only previously known binary in theKuiper belt.
Formation of Kuiper-belt binaries by dynamical friction and three-body encounters
It is shown that a transient binary forms when two large bodies penetrate one another's Hill sphere (the region where their mutual forces are larger than the tidal force of the Sun) and the loss of energy needed to stabilize the binary orbit can occur through dynamical friction from surrounding small bodies, or through the gravitational scattering of a third large body.
Discovery of the candidate Kuiper belt object 1992 QB1
THE apparent emptiness of the outer Solar System has been a long-standing puzzle for astronomers, as it contrasts markedly with the abundance of asteroids and short-period comets found closer to the
Two distinct populations of Kuiper-belt objects
The discovery of the first member of the Kuiper belt—a formerly hypothetical ancient reservoir of objects located beyond Neptune's orbit—started a revolution in our understanding of the outer Solar
Irregular Satellites in the Context of Planet Formation
All four giant planets in the solar system possess irregular satellites, characterized by large, highly eccentric and/or highly inclined orbits. These bodies were likely captured from heliocentric
Discovery of a Candidate Inner Oort Cloud Planetoid
We report the discovery of the minor planet (90377) Sedna, the most distant object ever seen in the solar system. Prediscovery images from 2001, 2002, and 2003 have allowed us to refine the orbit
The origin of the Kuiper Belt high-inclination population
Crystalline water ice on the Kuiper belt object (50000) Quaoar
It is concluded that Quaoar has been recently resurfaced, either by impact exposure of previously buried (shielded) ices or by cryovolcanic outgassing, or by a combination of these processes.
The formation of the Kuiper belt by the outward transport of bodies during Neptune's migration
It is shown that the objects currently observed in the dynamically cold Kuiper belt were most probably formed within ∼35 au and were subsequently pushed outward by Neptune's 1:2 mean motion resonance during its final phase of migration.
Accretion in the Early Outer Solar System
We describe calculations of the evolution of an ensemble of small planetesimals in the outer solar system. In a solar nebula with a mass of several times the minimum mass solar nebula, objects with
