Atmospheric Circulation of Tide-Locked Exoplanets [PDF]
Annual Review of Fluid Mechanics, 2019 Tide-locked planets are planets in which tidal stresses from the host star have spun down the planet's rotation to the point where its length of sidereal day equals its length of year. In a nearly circular orbit, such planets have a permanent dayside and a permanent nightside, leading to extreme heating contrasts.

Proceedings of the International Astronomical Union, 2019 AbstractThis paper reviews the basic equations used in the study of the tidal variations of the rotational and orbital elements of a system formed by one star and one close-in planet as given by the creep tide theory and Darwin’s constant time lag (CTL) theory.

EMPIRICAL TIDAL DISSIPATION IN EXOPLANET HOSTS FROM TIDAL SPIN-UP. [PDF]
Astron J, 2018 Stars with hot Jupiters (HJs) tend to rotate faster than other stars of the same age and mass. This trend has been attributed to tidal interactions between the star and planet.

Spin evolution of Earth-sized exoplanets, including atmospheric tides and core–mantle friction [PDF]
International Journal of Astrobiology, 2014 AbstractPlanets with masses between 0.1 and 10 M⊕are believed to host dense atmospheres. These atmospheres can play an important role on the planet's spin evolution, since thermal atmospheric tides, driven by the host star, may counterbalance gravitational tides. In this work, we study the long-term spin evolution of Earth-sized exoplanets.

Astronomy & Astrophysics, 2023 The spin–orbit angle, or obliquity, is a powerful observational marker that allows us to access the dynamical history of exoplanetary systems. For this study, we have examined the distribution of spin–orbit angles for close-in exoplanets and put it in a statistical context of tidal interactions between planets and their host stars.

Tidal Migration of Exoplanets around M Dwarfs: Frequency-dependent Tidal Dissipation [PDF]
The Astrophysical Journal, 2023 The orbital architectures of short-period exoplanet systems are shaped by tidal dissipation in their host stars. For low-mass M dwarfs whose dynamical tidal response comprises a dense spectrum of inertial modes at low frequencies, resolving the frequency

Self-consistent Dynamical and Chaotic Tides in the REBOUNDx Framework
The Astrophysical JournalAt high eccentricities, tidal forcing excites vibrational modes within orbiting bodies known as dynamical tides. In this paper, we implement the coupled evolution of these modes with the body’s orbit in the REBOUNDx framework, an extension to the popular

Empirical Constraints on Tidal Dissipation in Exoplanet Host Stars
The Astrophysical JournalThe orbits of short-period exoplanets are sculpted by tidal dissipation. However, the mechanisms and associated efficiencies of these tidal interactions are poorly constrained.

Polar Orbits around the Newly Formed Earth–Moon Binary System [PDF]
The Astrophysical JournalWe examine the dynamics and stability of circumbinary particles orbiting around the Earth–Moon binary system. The moon formed close to the Earth (semimajor axis a _EM ≈ 3 R _⊕ ) and expanded through tides to its current day semimajor axis ( a _EM = 60 R ...
