Tidal friction in early-type stars
Abstract
Theoretical and observational results related to tides in early-type stars are summarized. The results suggest that the tidal torque on an early-type star is concentrated near the boundary between the convective core and the radiative envelope, and that a train of gravity waves which is excited at this boundary outwardly transports the angular momentum removed from the fluid by the torque. Tidal despinning to synchronous rotation is shown to proceed from the outside to the inside of the star. The present model can account for the previous finding that Zahn's (1975, 1977) theory for tidal evolution in early-type close binaries is compatible with the observed rates of orbit circularization, while significantly underestimating the observed rates of spin synchronization.

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.
