Magnetohydrodynamics in hot Jupiters [PDF]

, 2021
PhD ThesisHot Jupiters are Jupiter-like exoplanets found in close-in orbits. This subjects them to high levels of stellar irradiance and is believed to tidally-lock them to their host stars, causing extreme day-night temperature differentials which in ...

A Uniform Search for Nearby Planetary Companions to Hot Jupiters in TESS Data Reveals Hot Jupiters Are Still Lonely

, 2023
We present the results of a uniform search for additional planets around all stars with confirmed hot Jupiters observed by the Transiting Exoplanet Survey Satellite (TESS) in its Cycle 1 survey of the southern ecliptic hemisphere.

Grain Alignment and Rotational Disruption by Radiative Torques in Exoplanet Atmospheres

The Astrophysical Journal, 2023
Dust clouds are ubiquitous in the atmospheres of hot Jupiters and affect their observable properties. The alignment of dust grains in the clouds and resulting dust polarization provide a promising way to study the magnetic fields of exoplanets. Moreover,

INFLATING HOT JUPITERS WITH OHMIC DISSIPATION [PDF]

The Astrophysical Journal, 2010
We present a new, magnetohydrodynamic mechanism for inflation of close-in giant extrasolar planets. The idea behind the mechanism is that current, which is induced through interaction of atmospheric winds and the planetary magnetic field, results in significant Ohmic dissipation of energy in the interior.

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 ...

TOI 564 b and TOI 905 b: Grazing and Fully Transiting Hot Jupiters Discovered by TESS [PDF]

, 2020
We report the discovery and confirmation of two new hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS): TOI 564 b and TOI 905 b.

Shallowness of circulation in hot Jupiters [PDF]

, 2022
The inflated radii of giant short-period extrasolar planets collectively indicate that the interiors of hot Jupiters are heated by some anomalous energy dissipation mechanism.

Emergent Spectral Fluxes of Hot Jupiters: An Abrupt Rise in Dayside Brightness Temperature Under Strong Irradiation

The Astronomical Journal, 2023
We study the emergent spectral fluxes of transiting hot Jupiters, using secondary eclipses from Spitzer. To achieve a large and uniform sample, we have reanalyzed all secondary eclipses for all hot Jupiters observed by Spitzer at 3.6 and/or 4.5 μ m.

ATMOSPHERIC SULFUR PHOTOCHEMISTRY ON HOT JUPITERS [PDF]

The Astrophysical Journal, 2009
We develop a new 1D photochemical kinetics code to address stratospheric chemistry and stratospheric heating in hot Jupiters. Here we address optically active S-containing species and CO2 at 1200 < T < 2000 K. HS (mercapto) and S2 are highly reactive species that are generated photochemically and thermochemically from H2S with peak abundances ...

Multi-Component MHD Model of Hot Jupiter Envelopes

Universe, 2021
A numerical model description of a hot Jupiter extended envelope based on the approximation of multi-component magnetic hydrodynamics is presented. The main attention is focused on the problem of implementing the completed MHD stellar wind model.
