Transiting exoplanets: From planet statistics to their physical nature

open access: yesEPJ Web of Conferences, 2011
The colloquium "Detection and Dynamics of Transiting Exoplanets" was held at the Observatoire de Haute-Provence and discussed the status of transiting exoplanet investigations in a 4.5 day meeting.

TrES-1 b: A Case Study in Detecting Secular Evolution of Exoplanet Orbits

open access: yesThe Astronomical Journal
We present a comprehensive analysis of transit, eclipse, and radial velocity data of the hot Jupiter TrES-1 b and confirm evidence of orbital variations on secular timescales.

Warm Jupiter Tidal Migration Can Spare Inner Planets; Hot Jupiter Tidal Migration May Not

open access: yesThe Astrophysical Journal
In this work, we investigate the dynamical survival of short-period inner planets during the high-eccentricity tidal migration of companion exterior giant planets.

Tidal dissipation in rotating and evolving giant planets with application to exoplanet systems [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2023
We study tidal dissipation in models of rotating giant planets with masses in the range 0.1 − 10MJ throughout their evolution. Our models incorporate a frequency-dependent turbulent effective viscosity acting on equilibrium tides (including its ...

Measuring the orbit shrinkage rate of hot Jupiters due to tides [PDF]

open access: yesAstronomy & Astrophysics, 2022
A tidal interaction between a star and a close-in exoplanet leads to shrinkage of the planetary orbit and eventual tidal disruption of the planet. Measuring the shrinkage of the orbits will allow for the tidal quality parameter of the star ($Q'_\star ...

Gas disk interactions, tides, and relativistic effects in the rocky planet formation at the substellar mass limit [PDF]

open access: yesAstronomy & Astrophysics, 2022
Context. The confirmed exoplanet population around very low mass stars is increasing considerable through data from the latest space missions and improvements in ground-based observations, particularly with the detection of Earth-like planets in the ...

Tidal Dissipation Regimes among the Short-period Exoplanets

open access: yesThe Astrophysical Journal Letters, 2023
The efficiency of tidal dissipation provides a zeroth-order link to a planet’s physical properties. For super-Earth and sub-Neptune planets in the range R _⊕ ≲ R _p ≲ 4 R _⊕ , particularly efficient dissipation (i.e., low tidal quality factors) may ...

Tidal Quality of the Hot Jupiter WASP-12b

open access: yesUniverse, 2022
WASP-12b stands out among the planets of its class of hot Jupiters because of the observed fast orbital decay attributed to tidal dissipation. The measured rate of the orbital period change is P⋅orb=−29±3ms/yr= −(9.2±1.0)×10−10s/s.

V456 Cyg: An eclipsing binary with tidally perturbed g-mode pulsations [PDF]

open access: yesAstronomy & Astrophysics, 2022
Context. Many well-known bright stars have been observed by the ongoing transiting exoplanet survey satellite (TESS) space mission. For several of them, these new data reveal previously unobserved variability, such as tidally perturbed pulsations in ...

Stability and Detectability of Exomoons Orbiting HIP 41378 f, a Temperate Jovian Planet with an Anomalously Low Apparent Density

open access: yesThe Astronomical Journal, 2023
Moons orbiting exoplanets (“exomoons”) may hold clues about planet formation, migration, and habitability. In this work, we investigate the plausibility of exomoons orbiting the temperate ( T _eq = 294 K) giant ( R = 9.2 R _⊕ ) planet HIP 41378 f, which ...
