Accretion Efficiency during Planetary Collisions
Open accessAbstract
We present the results of smoothed particle hydrodynamic simulations of collisions between two 0.10 M ⊕ differentiated planetary embryos with impact dynamics that are thought to be common to the late stage of terrestrial planet formation. At low impact velocities ( v imp / v esc < 1.5) and for direct collisions, the impacts are largely accretionary. Inelastic bouncing between embryos with varying degrees of erosion, followed by escape to infinity, is also a common outcome. For dynamical environments typical of most late-stage accretion models, we estimate that more than half of all collisions between like-sized planetary embryos do not result in accumulation into a larger embryo.

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.
