A Massive Hot Jupiter Orbiting a Metal-rich Early M Star Discovered in the TESS Full-frame Images
The Astronomical Journal, 2023 Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these extreme systems has remained under debate for decades. With the help of the TESS mission and ground-

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 ...

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.

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 ...

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 ...

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.
