Constraints on the Obliquities of Kepler Planet-Hosting Stars [PDF]
, 2017 Stars with hot Jupiters have obliquities ranging from 0-180 degrees, but relatively little is known about the obliquities of stars with smaller planets.

, 2021 The properties of a planetary system may be influenced by properties of the host star, such as its birth environment or age. Recently, a link has been found between a star's local phase space density in the Galaxy and the presence of a hot Jupiter: hot Jupiters are preferentially found around stars with higher local phase space densities.

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 ...

THERMAL PROCESSES GOVERNING HOT-JUPITER RADII [PDF]
The Astrophysical Journal, 2013 There have been many proposed explanations for the larger-than-expected radii of some transiting hot Jupiters, including either stellar or orbital energy deposition deep in the atmosphere or deep in the interior. In this paper, we explore the important influences on hot-Jupiter radius evolution of (i) additional heat sources in the high atmosphere, the

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,

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.

The Frequency of Hot Jupiters in the Galaxy
EPJ Web of Conferences, 2011 The frequency of Hot Jupiters around Galactic dwarf stars is determined from the results of the SuperLupus transit survey and realistic Monte Carlo simulations of the survey efficiency.

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.

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.
