Capture of the Sun's Oort Cloud from Stars in Its Birth Cluster
Abstract
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 what fraction of comets might transfer from the outer reaches of one stellar system to another. The simulations suggest that a substantial number of comets can be captured through this mechanism, which may explain why the number of bodies in the Oort cloud is larger than models predict.

Trans-Neptunian objects may provide a significant fraction of the Solar System's liquid water reservoir, perhaps collectively as much as on Earth.
“Given the overwhelming population of the Kuiper Belt (106 objects greater than a few tens of kilometers; Morbidelli and Levison, 2007) and Oort Cloud (∼4 × 1011 objects with a radius larger than 1 km; Levison et al., 2010), trans-neptunian objects may provide a significant fraction of the Solar System's liquid water reservoir, perhaps collectively even as much as on Earth (Desch et al., 2009).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
