The mutual orbit, mass, and density of transneptunian binary Gǃkúnǁ'hòmdímà (229762 2007 UK126)
Abstract We present high spatial resolution images of the binary transneptunian object Gǃkunǁ'homdima (229762 2007 UK126) obtained with the Hubble Space Telescope and with the Keck observatory onExpand
Characterization of Seven Ultra-wide Trans-Neptunian Binaries
The low-inclination component of the Classical Kuiper Belt is host to a population of extremely widely separated binaries. These systems are similar to other trans-Neptunian binaries (TNBs) in thatExpand
``TNOs are Cool'': A survey of the trans-Neptunian region . III. Thermophysical properties of 90482 Orcus and 136472 Makemake
Context. The goal of the Herschel open time programme “TNOs are Cooll” is to derive the physical and thermal properties for a large sample of Centaurs, and trans-Neptunian objects (TNOs), includingExpand
KCTF evolution of trans-neptunian binaries: Connecting formation to observation
Recent observational surveys of trans-neptunian binary (TNB) systems have dramatically increased the number of known mutual orbits. Our Kozai Cycle Tidal Friction (KCTF) simulations of syntheticExpand
“TNOs are Cool”: A survey of the trans-Neptunian region - XIII. Statistical analysis of multiple trans-Neptunian objects observed with Herschel Space Observatory
Context. Gravitationally bound multiple systems provide an opportunity to estimate the mean bulk density of the objects, whereas this characteristic is not available for single objects. Being aExpand
Estimating the density of intermediate size KBOs from considerations of volatile retention
Abstract By using a hydrodynamic atmospheric escape mechanism (Levi, A., Podolak, M. [2009]. Icarus 202, 681–693) we show how the unusually high mass density of Quaoar could have been predictedExpand
Spitzer Evidence for a Late Heavy Bombardment and the Formation of Urelites in {\eta} Corvi at ~1 Gyr
We have analyzed Spitzer and NASA/IRTF 2 - 35 \mum spectra of the warm, ~350 K circumstellar dust around the nearby MS star {\eta} Corvi (F2V, 1.4 \pm 0.3 Gyr). The spectra show clear evidence forExpand
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
Rotational properties of the binary and non-binary populations in the Trans-Neptunian belt
We present results for the short-term variability of Binary Trans-Neptunian Objects (BTNOs). We performed CCD photometric observations using the 3.58 m Telescopio Nazionale Galileo, the 1.5 m SierraExpand
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 albedo, size, and density of binary kuiper belt object (47171) 1999 TC36
We measured the system-integrated thermal emission of the binary Kuiper Belt object (47171 ) 1999 TC36, at wavelengths near 24 and 70 μm using the Spitzer Space Telescope. We fit these data and theExpand
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.

A Giant Impact Origin of Pluto-Charon
Hydrodynamic simulations are used to demonstrate that the formation of Pluto-Charon by means of a large collision is quite plausible, and suggest that collisions between 1000-kilometer-class objects occurred in the early inner Kuiper belt. Expand
Here we report Wide-Field Planetary Camera 2 observations of the Quaoar-Weywot Kuiper Belt binary. From these observations, we find that Weywot is on an elliptical orbit with an eccentricity of 0.14Expand
