Magnetic fields in non-convective regions of stars

J Braithwaite, HC Spruit - Royal Society Open Science, 2017 - royalsocietypublishing.org
We review the current state of knowledge of magnetic fields inside stars, concentrating on
recent developments concerning magnetic fields in stably stratified (zones of) stars, leaving …

Tidal dissipation in evolving low-mass and solar-type stars with predictions for planetary orbital decay

AJ Barker - Monthly Notices of the Royal Astronomical Society, 2020 - academic.oup.com
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 …

Orbital alignment of the eccentric warm Jupiter TOI-677 b

E Sedaghati, A Jordán, R Brahm… - The Astronomical …, 2023 - iopscience.iop.org
Warm Jupiters lay out an excellent laboratory for testing models of planet formation and
migration. Their separation from the host star makes tidal reprocessing of their orbits …

Tidal dissipation in planet-hosting stars: damping of spin–orbit misalignment and survival of hot Jupiters

D Lai - Monthly Notices of the Royal Astronomical Society, 2012 - academic.oup.com
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 …

Orbital decay of short-period exoplanets via tidal resonance locking

L Ma, J Fuller - The Astrophysical Journal, 2021 - iopscience.iop.org
A large fraction of known exoplanets have short orbital periods where tidal excitation of
gravity waves within the host star causes the planets' orbits to decay. We study the effects of …

Orbital decay of hot jupiters due to nonlinear tidal dissipation within solar-type hosts

R Essick, NN Weinberg - The Astrophysical Journal, 2015 - iopscience.iop.org
We study the orbital evolution of hot Jupiters due to the excitation and damping of tidally
driven g-modes within solar-type host stars. Linearly resonant g-modes (the dynamical tide) …

Nonlinear tides in close binary systems

NN Weinberg, P Arras, E Quataert… - The Astrophysical …, 2012 - iopscience.iop.org
We study the excitation and damping of tides in close binary systems, accounting for the
leading-order nonlinear corrections to linear tidal theory. These nonlinear corrections …

Orbital Decay of Hot Jupiters due to Weakly Nonlinear Tidal Dissipation

NN Weinberg, N Davachi, R Essick, H Yu… - The Astrophysical …, 2023 - iopscience.iop.org
We study tidal dissipation in hot Jupiter host stars due to the nonlinear damping of tidally
driven g-modes, extending the calculations of Essick & Weinberg to a wide variety of stellar …

Magnetic games between a planet and its host star: the key role of topology

A Strugarek, AS Brun, SP Matt… - The Astrophysical …, 2015 - iopscience.iop.org
Magnetic interactions between a star and a close-in planet are postulated to be a source of
enhanced emissions and to play a role in the secular evolution of the orbital system. Close …

Dynamical tides in compact white dwarf binaries: tidal synchronization and dissipation

J Fuller, D Lai - Monthly Notices of the Royal Astronomical …, 2012 - academic.oup.com
In compact white dwarf (WD) binary systems (with periods ranging from minutes to hours),
dynamical tides involving the excitation and dissipation of gravity waves play a dominant …
