Stellar evolution and tidal dissipation in REBOUNDx [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
ABSTRACT To study the post-main sequence evolution of the Solar system and exoplanetary systems more accurately and efficiently, we introduce two new features to reboundx, an extended library for the N-body integrator rebound. The first is a convenient parameter interpolator for coupling different physics and integrators using ...

Tidal Dissipation in Stratified and Semi-convective Regions of Giant Planets

open access: yesThe Astrophysical Journal, 2023
We study how stably stratified or semi-convective layers alter the tidal dissipation rates associated with the generation of internal waves in planetary interiors.

ON THE TIDAL DISSIPATION OF OBLIQUITY [PDF]

open access: yesThe Astrophysical Journal, 2013
We investigate tidal dissipation of obliquity in hot Jupiters. Assuming an initial random orientation of obliquity and parameters relevant to the observed population, the obliquity of hot Jupiters does not evolve to purely aligned systems. In fact, the obliquity evolves to either prograde, retrograde or 90^{o} orbits where the torque due to tidal ...

Tidal Dissipation in Stably Stratified and Semiconvective Regions of Rotating Giant Planets: Incorporating Coriolis Forces

open access: yesThe Astrophysical Journal, 2023
We study how stably stratified or semiconvective layers alter tidal dissipation rates associated with the generation of inertial, gravito-inertial, interfacial, and surface gravity waves in rotating giant planets.

Titan's strong tidal dissipation precludes a subsurface ocean. [PDF]

open access: yesNature
Introduction: The Cassini spacecraft orbited Saturn from 2004 to 2017, performing over a hundred flybys of Titan, Saturn’s largest moon. Ten of these flybys were dedicated to gravity measurements, yielding unprecedented insight into the moon’s interior.

Titan's spin state as a constraint on tidal dissipation. [PDF]

open access: yesSci Adv
Tidal dissipation in satellites affects their orbital and rotational evolution and their ability to maintain subsurface oceans. However, a satellite’s dissipation rate, parameterized by k 2 /Q , is hard to measure and is only known for the Moon and Io ...

Tidal Energy Dissipation [PDF]

open access: yesNature, 1917
IN regard to my estimate of viscous dissipation of oceanic energy in its bearing on the slowing of the earth's rotation (Proc. Roy. Soc., A, 93, p. 348), I quite assent to Mr. Jeffreys's position (NATURE, vol. xcix., p. 405, July 19, 1917) that it is still open to doubt whether the viscosity of the ocean causes a very appreciable part of the earth's ...

Numerical modeling of internal tides and submesoscale turbulence in the US Caribbean regional ocean

open access: yesScientific Reports, 2023
The US Caribbean ocean circulation is governed by an influx of Atlantic water through the passages between Puerto Rico, Hispaniola and the Virgin Islands, and an interplay of the Caribbean Sea water with the local topography of the region.

Tidally Excited Inertial Waves in Stars and Planets: Exploring the Frequency-dependent and Averaged Dissipation with Nonlinear Simulations

open access: yesThe Astrophysical Journal Letters, 2023
We simulate the nonlinear hydrodynamical evolution of tidally excited inertial waves in convective envelopes of rotating stars and giant planets modeled as spherical shells containing incompressible, viscous, and adiabatically stratified fluid.

Measuring tidal dissipation in giant planets from tidal circularization

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT In this project, we determined the constraints on the modified tidal quality factor, $Q_{\rm pl}^{\prime }$, of gas-giant planets orbiting close to their host stars. We allowed $Q_{\rm pl}^{\prime }$ to depend on tidal frequency, accounting for the multiple tidal waves with time-dependent frequencies simultaneously present on ...
