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.

Atmospheric Circulation of Tide-Locked Exoplanets [PDF]
Annual Review of Fluid Mechanics, 2018 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.

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

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.

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.

DREAM II. The spin-orbit angle distribution of close-in exoplanets under the lens of tides
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.

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.
