EVOLUTION OF OHMICALLY HEATED HOT JUPITERS [PDF]

open access: yesThe Astrophysical Journal, 2011
We present calculations of thermal evolution of Hot Jupiters with various masses and effective temperatures under Ohmic dissipation. The resulting evolutionary sequences show a clear tendency towards inflated radii for effective temperatures that give rise to significant ionization of alkali metals in the atmosphere, compatible with the trend of the ...

Single-star Warm-Jupiter Systems Tend to Be Aligned, Even around Hot Stellar Hosts: No T eff–λ Dependency

open access: yesThe Astrophysical Journal Letters
The stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters’ tidal detachment likely preserves their primordial obliquity.

The Nitrogen Chemistry in Hot Jupiters Atmosphere [PDF]

open access: yes, 2013
The atmosphere of hot Jupiters can be probed by primary transit and secondary eclipse spectroscopy. In order to constrain the atmospheric thermal structure and composition from observables, chemical models are necessary. Due to the intense UV irradiation, mixing and circulation, the chemical composition is maintained out of equilibrium and kinetic ...

The Formation of Double Hot Jupiter Systems through von Zeipel–Lidov–Kozai Migration

open access: yesThe Astrophysical Journal
The von Zeipel–Lidov–Kozai (ZLK) mechanism with tidal friction has been demonstrated as a promising avenue to generate hot Jupiters in stellar binary systems.

ON THE FORMATION OF HOT JUPITERS IN STELLAR BINARIES [PDF]

open access: yesThe 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 ...

Three-dimensional Orbital Architectures and Detectability of Adjacent Companions to Hot Jupiters

open access: yesThe Astrophysical Journal
The orbital properties of the (as yet) small population of hot Jupiters with nearby planetary companions provide valuable constraints on the past migration processes of these systems.

Magnetohydrodynamical Torsional Oscillations from Thermoresistive Instability in Hot Jupiters

open access: yesThe Astrophysical Journal, 2023
Hot Jupiter atmospheres may be subject to a thermoresistive instability where an increase in the electrical conductivity due to ohmic heating results in runaway of the atmospheric temperature.

A Third Star in the HAT-P-7 System and a New Dynamical Pathway to Misaligned Hot Jupiters

open access: yesThe Astrophysical Journal
The retrograde orbit of the hot Jupiter HAT-P-7b is suggestive of high-eccentricity (high-e) migration caused by dynamical interactions with a massive companion.
