Decaying orbit of the hot Jupiter WASP-12b: Confirmation with TESS observations
JD Turner, A Ridden-Harper… - The Astronomical …, 2021 - iopscience.iop.org
Abstract Theory suggests that the orbits of some close-in giant planets should decay due to
tidal interactions with their host stars. To date, WASP-12b is the only hot Jupiter reported to …

The Possible Tidal Demise of Kepler's First Planetary System
S Vissapragada, A Chontos… - The Astrophysical …, 2022 - iopscience.iop.org
We present evidence of tidally-driven inspiral in the Kepler-1658 (KOI-4) system, which
consists of a giant planet (1.1RJ, 5.9MJ) orbiting an evolved host star (2.9R⊙, 1.5M⊙) …

Evidence That the Occurrence Rate of Hot Jupiters around Sun-like Stars Decreases with Stellar Age
S Miyazaki, K Masuda - The Astronomical Journal, 2023 - iopscience.iop.org
We investigate how the occurrence rate of giant planets (minimum mass> 0.3 M Jup) around
Sun-like stars depends on the age, mass, and metallicity of their host stars. We develop a …

The EBLM Project—From False Positives to Benchmark Stars and Circumbinary Exoplanets
PFL Maxted, AHMJ Triaud, DV Martin - Universe, 2023 - mdpi.com
The EBLM project aims to characterise very-low-mass stars that are companions to solar-
type stars in eclipsing binaries. We describe the history and motivation for this project, the …

DREAM-II. The spin–orbit angle distribution of close-in exoplanets under the lens of tides
O Attia, V Bourrier, JB Delisle… - Astronomy & …, 2023 - aanda.org
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 …

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 …

Tidal dissipation due to the elliptical instability and turbulent viscosity in convection zones in rotating giant planets and stars
NB de Vries, AJ Barker… - Monthly Notices of the …, 2023 - academic.oup.com
Tidal dissipation in star–planet systems can occur through various mechanisms, among
which is the elliptical instability. This acts on elliptically deformed equilibrium tidal flows in …
