ON THE FORMATION OF HOT JUPITERS IN STELLAR BINARIES [PDF]
The Astrophysical Journal, 2012 We study the production of Hot Jupiters (HJs) in stellar binaries. We show that the "eccentric Kozai-Lidov" (EKL) mechanism can play a key role in the dynamical evolution of a star-planet-star triple system. We run a large set of Monte Carlo simulations including the secular evolution of the orbits, general relativistic precession, and tides, and we ...

Radiative equilibrium models of “hot Jupiters” [PDF]
Symposium - International Astronomical Union, 2004 We present an extension of our equilibrium model, initially applied to 51 Peg b (Goukenleuque et al. 2000), to other irradiated extrasolar planets with different orbital distances (up to 1 AU). The model yields the mean atmospheric thermal structure and predicts the reflected spectral flux as well as the thermal flux emerging from such planets, in the ...

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 ...

Occurrence rate of hot Jupiters orbiting red giant stars [PDF]
, 2023 Context. Hot Jupiters form an enigmatic class of object whose formation pathways are not yet clear. Determining their occurrence rates as a function of orbit, planet and stellar mass, and system age can be an important ingredient for understanding how ...

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.

The Nitrogen Chemistry in Hot Jupiters Atmosphere [PDF]
, 2013 International audienceThe atmosphere of hot Jupiters can be probed by primary transit andsecondary eclipse spectroscopy. In order to constrain the atmospheric thermalstructure and composition from observables, chemical models are ...

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 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 ...
