Medium-sized satellites of large Kuiper belt objects

  journal={arXiv: Earth and Planetary Astrophysics},
While satellites of mid- to small-Kuiper belt objects tend to be similar in size and brightness to their primaries, the largest Kuiper belt objects preferentially have satellites with small fractional brightness. In the two cases where the sizes and albedos of the small faint satellites have been measured, these satellites are seen to be small icy fragments consistent with collisional formation. Here we examine Dysnomia and Vanth, the satellites of Eris and Orcus, respectively. Using the… Expand

The Albedos, Sizes, Colors and Satellites of Dwarf Planets Compared with Newly Measured Dwarf Planet 2013 FY27
2013 FY27 is the ninth intrinsically brightest Trans-Neptunian Object (TNO). We observed 2013 FY27 at thermal wavelengths with ALMA and in the optical with Magellan to determine its size and albedoExpand
Trans-Neptunian objects and Centaurs at thermal wavelengths
Abstract The thermal emission of Trans-Neptunian objects and Centaurs has been observed at mid- and far-infrared wavelengths—with the biggest contributions coming from the Spitzer and Herschel spaceExpand
Potential for Solar System Science with the ngVLA.
Radio wavelength observations of solar system bodies are a powerful method of probing many characteristics of those bodies. From surface and subsurface, to atmospheres (including deep atmospheres ofExpand
Early formation of moons around large trans-Neptunian objects via giant impacts
Recent studies1,2 have revealed that all large (over 1,000 km in diameter) trans-Neptunian objects (TNOs) form satellite systems. Although the largest Plutonian satellite, Charon, is thought to be anExpand
Transneptunian Space and the Post-Pluto Paradigm
The Pluto system is an archetype for the multitude of icy dwarf planets and accompanying satellite systems that populate the vast volume of the solar system beyond Neptune. New Horizons’ explorationExpand
A stellar occultation by Vanth, a satellite of (90482) Orcus
Abstract A stellar occultation by the large trans-Neptunian object (90482) Orcus was predicted to occur on 2017 March 07. Observations were made at five sites in North and South America: the 0.6-mExpand
Astrometric and photometric observations of six brightest trans-Neptunian objects at the Kyiv comet station
In this work we focused on observations of six trans-Neptunian objects (TNOs) whose apparent magnitudes are brighter than 20m. We present the results of astrometric and photometric observations ofExpand
On the Origin of the Pluto System
For six decades following its discovery, Pluto was the only known Sun-orbiting world in the dynamical vicinity of Neptune. An early origin concept postulated that Neptune originally had two largeExpand
The Eris/Dysnomia system I: The orbit of Dysnomia
Abstract We present new results on the Eris/Dysnomia system including analysis of new images from the WFC3 instrument on the Hubble Space Telescope (HST). Seven HST orbits were awarded to programExpand
JWST/NIRSpec Prospects on Transneptunian Objects
The transneptunian region has proven to be a valuable probe to test models of the formation and evolution of the solar system. To further advance our current knowledge of these early stages requiresExpand


Satellites of the largest Kuiper Belt objects
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 areExpand
The density of mid-sized Kuiper belt object 2002 UX25 and the formation of the dwarf planets
The formation of the largest objects in the Kuiper belt, with measured densities of ~1.5 g cm^(–3) and higher, from the coagulation of small bodies, with measured densities below 1 g cm^(–3), isExpand
The Density of Mid-sized Kuiper Belt Objects from ALMA Thermal Observations
The densities of mid-sized Kuiper Belt objects (KBOs) are a key constraint in understanding the assembly of objects in the outer solar system. These objects are critical for understanding theExpand
Interpreting the densities of the Kuiper belt's dwarf planets
Kuiper Belt objects with absolute magnitude less than 3 (radius $\gtrsim$500 km), the dwarf planets, have a range of different ice/rock ratios, and are more rock-rich than their smaller counterparts.Expand
The Formation of the Collisional Family Around the Dwarf Planet Haumea
Haumea, a rapidly rotating elongated dwarf planet ({approx}1500 km in diameter), has two satellites and is associated with a 'family' of several smaller Kuiper Belt objects (KBOs) in similar orbits.Expand
Orbits and Masses of the Satellites of the Dwarf Planet Haumea (2003 EL61)

A large fraction of ~100 km class low-inclination objects in the classical Kuiper Belt (KB) are binaries with comparable masses and a wide separation of components. A favored model for theirExpand
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.
