Out of the Oort Cloud Long-period comets originate from the Oort cloud, a vast reservoir of icy bodies that surrounds the solar system. These bodies are thought to be remnants from the formation of the solar system. But did they all form in the Sun's protoplanetary disk, or could they have been generated in the protoplanetary disks of other stars in the cluster where the Sun probably formed? Levison et al. (p. 187, published online 10 June) used detailed numerical simulations to investigate… 
The Destruction of an Oort Cloud in a rich stellar cluster
It is possible that the formation of the Oort Cloud dates back to the earliest epochs of solar system history. At that time, the Sun was almost certainly a member of the stellar cluster, where it was

Abstract It is shown that a mechanism involving only random motion of the sun with respect to the surrounding star field can account for the ~1 per 25 Myr characteristic frequency of large cometary
Finding the imprints of stellar encounters in long-period comets
The solar system's Oort cloud can be perturbed by the Galactic tide and by individual passing stars. These perturbations can inject Oort cloud objects into the inner parts of the solar system, where
Eight billion asteroids in the Oort cloud
The Oort cloud is usually thought of as a collection of icy comets inhabiting the outer reaches of the Solar system, but this picture is incomplete. We use simulations of the formation of the Oort
Observations indicate that the gaseous circumstellar disks around young stars vary significantly in size, ranging from tens to thousands of AU. Models of planet formation depend critically upon the
Stellar Flybys Interrupting Planet–Planet Scattering Generates Oort Planets
Wide-orbit exoplanets are starting to be detected, and planetary formation models are under development to understand their properties. We propose a population of "Oort" planets around other stars,
Exploring the role of the Sun's motion in terrestrial comet impacts
The cratering record on the Earth and Moon shows that our planet has been exposed to high velocity impacts for much or all of its existence. Some of these craters were produced by the impact of long
Oort cloud asteroids: collisional evolution, the Nice Model, and the Grand Tack
If the Solar system had a history of planet migration, the signature of that migration may be imprinted on the populations of asteroids and comets that were scattered in the planets' wake. Here, we
A Model for the Common Origin of Jupiter Family and Halley Type Comets
A numerical simulation of the Oort cloud is used to explain the observed orbital distributions and numbers of Jupiter-family (JF) and Halley-type (HT) short-period (SP) comets. Comets are given


Capture of comets during the evolution of a star cluster and the origin of the Oort Cloud
It is generally assumed that the Solar System is surrounded by a swarm of comets, the so-called Oort Cloud, which contains approximately 1011 members. The observed comets belong to a small subsection
Reassessing the Source of Long-Period Comets
Numerical simulations show that the inner Oort Cloud is a major source of long-period comets that cross Earth’s orbit, and they are an important, if not the dominant, source of known LPCs.
The formation of Uranus and Neptune in the Jupiter–Saturn region of the Solar System
The results of model calculations are reported that demonstrate that solid cores of the gas-giant planets Jupiter and Saturn will have been gravitationally scattered outwards as Jupiter, and perhaps Saturn, accreted nebular gas.
The Formation and Extent of the Solar System Comet Cloud
The formation of the solar system comet cloud and its subsequent evolution over an interval equal to the age of the solar system are simulated. Assuming that the comets formed in the outer planetary
Stellar encounters as the origin of distant Solar System objects in highly eccentric orbits
It is shown that a passing star probably scattered Sedna from the Kuiper belt into its observed orbit, and the likelihood that a planet at 60–80 au can be scattered into Sedna's orbit is about 50 per cent; this estimate depends critically on the geometry of the fly-by.
The origin of Pluto's orbit: implications for the
The origin of the highly eccentric, inclined, and resonance-locked orbit of Pluto has long been a puzzle. A possible explanation has been proposed recently which suggests that these extraordinary
Embedded Clusters in Molecular Clouds
The first extensive catalog of galactic embedded clusters is compiled, finding that the embedded cluster birthrate exceeds that of visible open clusters by an order of magnitude or more indicating a high infant mortality rate for protocluster systems.
Modeling the Formation of Giant Planet Cores I: Evaluating Key Processes
One of the most challenging problems we face in our understanding of planet formation is how Jupiter and Saturn could have formed before the the solar nebula dispersed. The most popular model of
The Demographics of Long-Period Comets
The absolute magnitude and perihelion distributions of long-period comets are derived, using data from the Lincoln Near-Earth Asteroid Research (LINEAR) survey. The results are surprising in three
