Atmospheric Dynamics of Hot Exoplanets [PDF]

Annual Review of Earth and Planetary Sciences, 2015
The characterization of exoplanetary atmospheres has come of age in the past decade, as astronomical techniques now allow for albedos, chemical abundances, temperature profiles and maps, rotation periods, and even wind speeds to be measured. Atmospheric dynamics sets the background state of density, temperature, and velocity that determines or ...

General circulation modelling of close-in extrasolar giant planets [PDF]

, 2011
PhDA large fraction of the extrasolar planets detected so far are giant planets that have such short orbital periods (a few days) that they are thought to be tidally-synchronised with the host star. Such orbits lead to permanent day/night sides on the

Kepler-80 Revisited: Assessing the Participation of a Newly Discovered Planet in the Resonant Chain

The Astronomical Journal, 2023
In this paper, we consider the chain of resonances in the Kepler-80 system and evaluate the impact that the additional member of the resonant chain discovered by Shallue & Vanderburg has on the dynamics of the system and the physical parameters that can ...

Workshop Summary: Exoplanet Orbits and Dynamics

Publications of the Astronomical Society of the Pacific, 2023
Abstract Exoplanetary systems show a wide variety of architectures, which can be explained by different formation and dynamical evolution processes. Precise orbital monitoring is mandatory to accurately constrain their orbital and dynamical parameters.

Dynamical Evolution of Closely Packed Multiple Planetary Systems Subject to Atmospheric Mass Loss

The Astronomical Journal, 2023
A gap in exoplanets’ radius distribution has been widely attributed to the photoevaporation threshold of their progenitors’ gaseous envelope. Giant impacts can also lead to substantial mass loss.

Tidal Dissipation Regimes among the Short-period Exoplanets

The 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 ...

exoMMR: A New Python Package to Confirm and Characterize Mean Motion Resonances

The Astronomical Journal, 2023
The study of orbital resonances allows for the constraint of planetary properties of compact systems. We can predict a system’s resonances by observing the orbital periods of the planets, as planets in or near mean motion resonance (MMR) have period ...
