Models of giant planet formation with migration and disc evolution

Abstract

We present a new model of giant planet formation that extends the core-accretion model of Pollack et al. (1996, Icarus, 124, 62) to include migration, disc evolution and gap formation. We show that taking these effects into account can lead to much more rapid formation of giant planets, making it compatible with the typical disc lifetimes inferred from observations of young circumstellar discs. This speed up is due to the fact that migration prevents the severe depletion of the feeding zone as observed in in situ calculations. Hence, the growing planet is never isolated and it can reach cross-over mass on a much shorter timescale. To illustrate the range of planets that can form in our model, we describe a set of simulations in which we have varied some of the initial parameters and compare the final masses and semi-major axes with those inferred from observed extra-solar planets.

  • A hot Jupiter that underwent disk migration may have an intermediate composition if it accreted gas along the way.

    “A hot Jupiter that underwent disk migration may have an intermediate composition if it accreted gas along the way (e.g., Alibert et al. 2005).”

    From Origins of Hot Jupiters (2018) · cites this paper as Alibert et al. 2005

    The Introduction links close-in giant planets to inward disk migration, and §3.2 models a migrating giant that accretes both gas and planetesimals, with its heavy-element content depending partly on the accreted gas. But that illustrated planet ends at about 2.5 AU, not in a hot-Jupiter orbit, and the paper does not describe its composition as intermediate. (LLM, conf=0.82)

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.
