OHMIC DISSIPATION IN THE ATMOSPHERES OF HOT JUPITERS [PDF]

The Astrophysical Journal, 2010
Hot Jupiter atmospheres exhibit fast, weakly-ionized winds. The interaction of these winds with the planetary magnetic field generates drag on the winds and leads to ohmic dissipation of the induced electric currents. We study the magnitude of ohmic dissipation in representative, three-dimensional atmospheric circulation models of the hot Jupiter HD ...

Diffusive Equilibrium: Modeling Anisotropic Maxwellian and Kappa Field Line Distributions in Io's Plasma Torus Using Multi‐Fluid and Kinetic Approaches

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Modeling density distributions along Jupiter's magnetic field lines is essential for understanding the Io plasma torus, moon plasma interactions, and plasma throughout the magnetosphere. This study compares multi‐fluid and kinetic approaches to diffusive equilibrium and the effects of different plasma distribution functions and anisotropy.

Tidal oscillations of rotating hot Jupiters [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We calculate small amplitude gravitational and thermal tides of uniformly rotating hot Jupiters composed of a nearly isentropic convective core and a geometrically thin radiative envelope. We treat the fluid in the convective core as a viscous fluid and solve linearized Navier–Stokes equations to obtain tidal responses of the ...

ATMOSPHERIC HEAT REDISTRIBUTION ON HOT JUPITERS [PDF]

The Astrophysical Journal, 2013
Infrared lightcurves of transiting hot Jupiters present a trend in which the atmospheres of the hottest planets are less efficient at redistributing the stellar energy absorbed on their daysides---and thus have a larger day-night temperature contrast---than colder planets.

Observed Latitudinal, Longitudinal and Temporal Variability of Io's Atmosphere Simulated by a Purely Sublimation Driven Atmosphere

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract How much of Io's SO2 ${\text{SO}}_{2}$ atmosphere is driven by volcanic outgassing or sublimation of SO2 ${\text{SO}}_{2}$ surface frost is a question with a considerable history. We develop a time dependent surface temperature model including thermal inertia and the exact celestial geometry to model the radiation driven global structure and ...

ACCRETION OF ROCKY PLANETS BY HOT JUPITERS [PDF]

The Astrophysical Journal, 2011
The observed population of Hot Jupiters displays a stunning variety of physical properties, including a wide range of densities and core sizes for a given planetary mass. Motivated by the observational sample, this paper studies the accretion of rocky planets by Hot Jupiters, after the Jovian planets have finished their principal migration epoch and ...

New avenues for thermal inversions in atmospheres of hot Jupiters [PDF]

Monthly notices of the Royal Astronomical Society, 2019
Thermal emission spectra of hot Jupiters have led to key constraints on thermal inversions (or 'stratospheres') in their atmospheres with important implications for their atmospheric processes.

Long-term Variations in the Orbital Period of Hot Jupiters from Transit-timing Analysis Using TESS Survey Data

The Astrophysical Journal Supplement Series
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters.

Investigation of nano‐SiO2 and nano‐Al2O3 additions in glaze formulation for Brazilian polished glazed porcelain stoneware tile

International Journal of Applied Ceramic Technology, Volume 22, Issue 4, July/August 2025.
Abstract The ceramic‐glaze for polished glazed porcelain stoneware tile is directly linked in determining the quality of the final product, as its characteristics significantly influence surface properties after polishing, including stain resistance, abrasion resistance, and chemical resistance.
