The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

Astrophysical fluid bodies that orbit close to one another induce tidal distortions and flows
that are subject to dissipative processes. The spin and orbital motions undergo a coupled …

We study tidal dissipation in stars with masses in the range 0.1–1.6 M⊙ throughout their
evolution, including turbulent effective viscosity acting on equilibrium tides and inertial …

When orbiting hotter stars, hot Jupiters are often highly inclined relative to their host star
equator planes. By contrast, hot Jupiters orbiting cooler stars are more aligned. Prior …

We present numerical simulations of internal gravity waves (IGW) in a star with a convective
core and extended radiative envelope. We report on amplitudes, spectra, dissipation, and …

Many core-collapse supernova (SN) progenitors show indications of enhanced pre-SN mass
loss and outbursts, some of which could be powered by wave energy transport within the …

Many of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot
Jupiter for which orbital decay has been directly detected is WASP-12, for which transit …

While cooler giant planets are often observed with nonzero eccentricities, the short-period
circular orbits of hot Jupiters suggest that they lose orbital energy and angular momentum …

Observations of hot Jupiters around solar-type stars with very short orbital periods (∼ 1 d)
suggest that tidal dissipation in such stars is not too efficient so that these planets can …
