Atmospheric dynamics of hot giant planets and brown dwarfs

AP Showman, X Tan, V Parmentier - Space Science Reviews, 2020 - Springer
Groundbased and spacecraft telescopic observations, combined with an intensive modeling
effort, have greatly enhanced our understanding of hot giant planets and brown dwarfs over …

Atmospheric regimes and trends on exoplanets and brown dwarfs

X Zhang - Research in Astronomy and Astrophysics, 2020 - iopscience.iop.org
A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …

2D retrieval frameworks for hot Jupiter phase curves

YK Feng, MR Line, JJ Fortney - The Astronomical Journal, 2020 - iopscience.iop.org
Spectroscopic phase curves provide unique access to the three-dimensional properties of
transiting exoplanet atmospheres. However, a modeling framework must be developed to …

The inhomogeneity effect. ii. Rotational and orbital states impact planetary cooling

X Zhang - The Astrophysical Journal, 2023 - iopscience.iop.org
We generalize the theory of the inhomogeneity effect to enable comparison among different
inhomogeneous planets. A metric of inhomogeneity based on the cumulative distribution …

Grain growth in esca** atmospheres: implications for the radius inflation of super-puffs

K Ohno, YA Tanaka - The Astrophysical Journal, 2021 - iopscience.iop.org
Super-puffs—low-mass exoplanets with extremely low bulk density—are attractive targets for
exploring their atmospheres and formation processes. Recent studies suggested that the …

Dynamics of Colombo's top: tidal dissipation and resonance capture, with applications to oblique super-Earths, ultra-short-period planets and inspiraling hot Jupiters

Y Su, D Lai - Monthly Notices of the Royal Astronomical Society, 2022 - academic.oup.com
We present a comprehensive theoretical study on the spin evolution of a planet under the
combined effects of tidal dissipation and gravitational perturbation from an external …

Warm Jupiters Beyond the Tidal Synchronization Limit may Exhibit a Wide Range of Secondary Eclipse Depths

E Rauscher, NB Cowan, R Luger - The Astronomical Journal, 2023 - iopscience.iop.org
With the JWST we can now characterize the atmospheres of longer-orbit planets, but this
moves us into a regime where we cannot assume that tidal forces from the star have eroded …

Excitation of planetary obliquities through planet–disk interactions

S Millholland, K Batygin - The Astrophysical Journal, 2019 - iopscience.iop.org
The tilt of a planet's spin axis off its orbital axis (" obliquity") is a basic physical characteristic
that plays a central role in determining the planet's global circulation and energy …

Atmospheres on nonsynchronized eccentric-tilted exoplanets. I. Dynamical regimes

K Ohno, X Zhang - The Astrophysical Journal, 2019 - iopscience.iop.org
Relatively long-period, nonsynchronized planets—such as warm Jupiters—potentially retain
the primordial rotation, eccentricity, and obliquity that might encapsulate information on …

Dynamics of Colombo's Top: Generating Exoplanet Obliquities from Planet–Disk Interactions

Y Su, D Lai - The Astrophysical Journal, 2020 - iopscience.iop.org
Large planetary spin–orbit misalignments (obliquities) may strongly influence atmospheric
circulation and tidal heating in a planet. A promising avenue to generate obliquities is via …
