Origins of Hot Jupiters [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2018
Hot Jupiters were the first exoplanets to be discovered around main sequence stars and astonished us with their close-in orbits. They are a prime example of how exoplanets have challenged our textbook, solar-system inspired story of how planetary systems form and evolve.

Orbital Decay of Hot Jupiters due to Weakly Nonlinear Tidal Dissipation

open access: yesThe Astrophysical Journal, 2023
We study tidal dissipation in hot Jupiter host stars due to the nonlinear damping of tidally driven g -modes, extending the calculations of Essick & Weinberg to a wide variety of stellar host types. This process causes the planet’s orbit to decay and has

INFLATING HOT JUPITERS WITH OHMIC DISSIPATION [PDF]

open access: yesThe 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.

A Spin-Orbit Alignment for the Hot Jupiter HATS-3b [PDF]

open access: yes, 2014
We have measured the alignment between the orbit of HATS-3b (a recently discovered, slightly inflated Hot Jupiter) and the spin-axis of its host star.

ATMOSPHERIC SULFUR PHOTOCHEMISTRY ON HOT JUPITERS [PDF]

open access: yesThe 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 ...

Hot Jupiters, Cold Kinematics

open access: yes, 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]

open access: yesSymposium - 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 ...

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

open access: yesThe 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.

HAT-P-5b: A Jupiter-like hot Jupiter Transiting a Bright Star [PDF]

open access: yes, 2007
We report the discovery of a planet transiting a moderately bright (V = 12.00) G star, with an orbital period of 2.788491 +/-0.000025 days. From the transit light curve we determine that the radius of the planet is Rp = 1.257 +/- 0.053 RJup. HAT-P-5b has

HATS-15 b and HATS-16 b: Two massive planets transiting old G dwarf stars [PDF]

open access: yes, 2015
We report the discovery of HATS-15 b and HATS-16 b, two massive transiting extrasolar planets orbiting evolved ($\sim 10$ Gyr) main-sequence stars. The planet HATS-15 b, which is hosted by a G9V star ($V=14.8$ mag), is a hot Jupiter with mass of $2.17 ...
