Origin and evolution of the cometary reservoirs
L Dones, R Brasser, N Kaib, H Rickman - Space Science Reviews, 2015 - Springer
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 …

Neptune's orbital migration was grainy, not smooth
D Nesvorný, D Vokrouhlický - The Astrophysical Journal, 2016 - iopscience.iop.org
ABSTRACT The Kuiper Belt is a population of icy bodies beyond the orbit of Neptune. The
complex orbital structure of the Kuiper Belt, including several categories of objects inside …

Impact craters on Pluto and Charon indicate a deficit of small Kuiper belt objects
The flyby of Pluto and Charon by the New Horizons spacecraft provided high-resolution
images of cratered surfaces embedded in the Kuiper belt, an extensive region of bodies …

Origin of Earth's water: chondritic inheritance plus nebular ingassing and storage of hydrogen in the core
Recent developments in planet formation theory and measurements of low D/H in deep
mantle material support a solar nebula source for some of Earth's hydrogen. Here we …

The tectonigral pathway regulates appetitive locomotion in predatory hunting in mice
Appetitive locomotion is essential for animals to approach rewards, such as food and prey.
The neuronal circuitry controlling appetitive locomotion is unclear. In a goal-directed …

Comets as collisional fragments of a primordial planetesimal disk
A Morbidelli, H Rickman - Astronomy & Astrophysics, 2015 - aanda.org
Context. The Rosetta mission and its exquisite measurements have revived the debate on
whether comets are pristine planetesimals or collisionally evolved objects. Aims. We …

Initial planetesimal sizes and the size distribution of small Kuiper belt objects
HE Schlichting, CI Fuentes… - The Astronomical Journal, 2013 - iopscience.iop.org
ABSTRACT The Kuiper Belt is a remnant from the early solar system and its size distribution
contains many important constraints that can be used to test models of planet formation and …

Debris disk size distributions: steady state collisional evolution with Poynting-Robertson drag and other loss processes
MC Wyatt, CJ Clarke, M Booth - Celestial Mechanics and Dynamical …, 2011 - Springer
We present a new scheme for determining the shape of the size distribution, and its
evolution, for collisional cascades of planetesimals undergoing destructive collisions and …
