Tidal torques on accretion discs in binary systems with extreme mass ratios

Lin, D. N. C., Papaloizou, J.·1979·Monthly Notices of the Royal Astronomical Society

Abstract

This paper investigates the tidal transport of angular momentum in accretion disc flow in a close binary system with small mass ratio, q. We demonstrate that the disc can only be tidally truncated if q is greater than the inverse of the Reynolds number. We derive the existence of a strong 2:1 resonance. Near the resonance, a spiral dissipation pattern is expected. If the Reynolds number is greater than ∼q−2, a dissipation and angular momentum loss from the disc may be sufficient to truncate it at the resonance. Finally we discuss the application of these results to dwarf novae.

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.
