Abstract

The process of gap formation by a growing planetary embryo embedded in a planetesimal disk is considered. It is shown that there exists a single parameter characterizing this process, which represents the competition between the gravitational influence of the embryo and planetesimal-planetesimal scattering. For realistic assumptions about the properties of the planetesimal disk and the planetary embryo, a gap is opened long before the embryo can accrete all the bodies within its region of influence. The implication of this result is that the embryo slows its growth considerably and, thus, large bodies formed during the coagulation stage should be less massive than is usually assumed. For conditions expected at 1 AU in the solar protoplanetary disk, gap formation is expected to occur around bodies of mass ≲10 24 g. The effect of protoplanetary radial migration is also discussed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • For satellites with r_H >> r_gap, the timescale for scattering particles out of the corotation zone is smaller than the timescale for viscous diffusion to bring particles back into the corotation zone, so the satellite begins to clear its corotation zone.

    “For satellites with r H r gap , the timescale for scattering particles out of the corotation zone is smaller than the timescale for viscous diffusion to bring particles back into the corotation zone.Thus, the satellite begins to clear its corotation zone (see also Lissauer et al. 1981;Hourigan & Ward 1984;Rafikov 2001).”

  • More detailed treatments derive some form of the radial diffusion equation across the gap and solve explicitly for the surface density distribution and the half-width of the gap.

    “More detailed treatments derive some form of the radial diffusion equation across the gap and solve explicitly for the surface density distribution and the half-width of the gap (e.g., Hourigan & Ward 1984;Rafikov 2001).”

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.
