Exploring exoplanet dynamics with JWST: Tides, rotation, rings, and moons. [PDF]
Proc Natl Acad Sci U S AAlthough nearly 6,000 exoplanets are currently known, in most cases, our knowledge is limited to a handful of the planet’s orbital characteristics and bulk properties such as radius and mass. The James Webb Space Telescope (JWST) can expand our knowledge not only by probing exoplanet atmospheres but also by measuring additional orbital and physical ...

Tides on Other Earths: Implications for Exoplanet and Palaeo‐Tidal Simulations [PDF]
Geophysical Research Letters, 2020 AbstractA key controller of a planet's rotational evolution, and hence habitability, is tidal dissipation, which on Earth is dominated by the ocean tides. Because exoplanet or deep‐time Earth topographies are unknown, a statistical ensemble is used to constrain possible tidal dissipation rates on an Earth‐like planet.

An Apparently Eccentric Orbit of the Exoplanet WASP-12 b as a Radial Velocity Signature of Planetary-induced Tides in the Host Star [PDF]
The Astrophysical Journal, 2020 Abstract Massive exoplanets on extremely tight orbits, such as WASP-12 b, induce equilibrium tides in their host stars. Following the orbital motion of the planet, the tidal fluid flow in the star can be detected with the radial velocity method.

Impact of Tides on the Potential for Exoplanets to Host Exomoons [PDF]
The Astronomical Journal, 2020 Abstract Exomoons may play an important role in determining the habitability of worlds outside of our solar system. They can stabilize conditions, alter the climate by breaking tidal locking with the parent star, drive tidal heating, and perhaps even host life themselves. However, the ability of an exoplanet to sustain an exomoon depends

Exoplanets Torqued by the Combined Tides of a Moon and Parent Star [PDF]
The Astronomical Journal, 2018 Abstract In recent years, there has been interest in Earth-like exoplanets in the habitable zones of low-mass stars (∼0.1–0.6 M ⊙). Furthermore, it has been argued that a large moon may be important for stabilizing conditions on a planet for life.

Do tides destabilize Trojan exoplanets? [PDF]
Icarus, 2022 One outstanding problem in extrasolar planet studies is why no co-orbital exoplanets have been found, despite numerous searches among the many known planetary systems, many of them in other mean-motion resonances. Here we examine the hypothesis that dissipation of energy by tides in Trojan planets is preventing their survival.

Implications of Tides for Life on Exoplanets [PDF]
Astrobiology, 2018 As evident from the nearby examples of Proxima Centauri and TRAPPIST-1, Earth-sized planets in the habitable zone of low-mass stars are common. Here, we focus on such planetary systems and argue that their (oceanic) tides could be more prominent due to stronger tidal forces.
