Magnetohydrodynamical Torsional Oscillations from Thermoresistive Instability in Hot Jupiters

The Astrophysical Journal, 2023
Hot Jupiter atmospheres may be subject to a thermoresistive instability where an increase in the electrical conductivity due to ohmic heating results in runaway of the atmospheric temperature.

Is the Atmosphere of the Ultra-hot Jupiter WASP-121 b Variable?

The Astrophysical Journal Supplement Series
We present a comprehensive analysis of the Hubble Space Telescope observations of the atmosphere of WASP-121 b, an ultra-hot Jupiter. After reducing the transit, eclipse, and phase-curve observations with a uniform methodology and addressing the biases ...

The Nitrogen Chemistry in Hot Jupiters Atmosphere [PDF]

, 2013
The atmosphere of hot Jupiters can be probed by primary transit and secondary eclipse spectroscopy. In order to constrain the atmospheric thermal structure and composition from observables, chemical models are necessary. Due to the intense UV irradiation, mixing and circulation, the chemical composition is maintained out of equilibrium and kinetic ...

On the heat redistribution of the hot transiting exoplanet WASP-18b

, 2013
The energy deposition and redistribution in hot Jupiter atmospheres is not well understood currently, but is a major factor for their evolution and survival.

High Temperature Photochemistry in the Atmosphere of HD189733b [PDF]

, 2010
Recent infrared spectroscopy of hot exoplanets is beginning to reveal their atmospheric composition. Deep with in the planetary atmosphere, the composition is controlled by thermochemical equilibrium.

Diagnosing the Atmosphere of Jupiter's Volcanic Moon Io Using Energetic Neutral Atoms (ENAs)

Geophysical Research Letters
During a Juno spacecraft encounter with Jupiter's volcanic moon Io (30 December 2023), the Jupiter Energetic Particle Detector Instrument (JEDI) observed Energetic Neutral Atoms (ENAs) of >150 keV oxygen and sulfur (O + S) coming from Io's mostly ...

A Correlation Between Stellar Activity and Hot Jupiter Emission Spectra [PDF]

, 2010
We present evidence for a correlation between the observed properties of hot Jupiter emission spectra and the activity levels of the host stars measured using Ca II H & K emission lines.
