Orbital Evolution and Migration of Giant Planets: Modeling Extrasolar Planets
Open accessAbstract
Giant planets in circumstellar disks can migrate inward from their initial (formation) positions. Radial migration is caused by inward torques between the planet and the disk, by outward torques between the planet and the spinning star, and by outward torques due to Roche lobe overflow and consequent mass loss from the planet. We present self-consistent numerical considerations of the problem of migrating giant planets. Summing torques on planets for various physical parameters, we find that Jupiter-mass planets can stably arrive and survive at small heliocentric distances, thus reproducing observed properties of some of the recently discovered extrasolar planets. Inward migration timescales can be approximately equal to or less than disk lifetimes and star spindown timescales. Therefore, the range of fates of massive planets is broad and generally comprises three classes: (I) planets that migrate inward too rapidly and lose all their mass; (II) planets that migrate inward, lose some but not all of their mass, and survive in very small orbits; and (III) planets that do not lose any mass. Some planets in class III do not migrate very far from their formation locations. Our results show that there is a wide range of possible fates for Jupiter-mass planets for both final heliocentric distance and final mass.

An inward migrating hot Jupiter can sustain its close-in orbit and avoid infall during the disk lifetime by extracting angular momentum from its star via tides.
“In the former mechanism, an inward migrating hot Jupiter can sustain its close-in orbit and avoid infall during the disk lifetime by extracting angular momentum from its star via tides (Trilling et al. 1998).”
From Origins of Hot Jupiters (2018) · cites this paper as Trilling et al. 1998
Section 4, “Torques from the Spinning Star” (page unavailable), says stellar tides exert an outward torque that slows the star and moves the planet outward. But Section 7, “Discussion” (page unavailable), says stellar tidal torques alone cannot reverse inward migration before infall unless the disk dissipates; survival close to the star depends on the combination of torques. The claim overstates tides as a sufficient way to avoid infall during the disk lifetime. (LLM, conf=0.85)

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.
