Annual 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.

The Atmospheric Circulation of Ultra-hot Jupiters [PDF]
The Astrophysical Journal, 2019 Abstract Recent observations of ultra-hot Jupiters with dayside temperatures in excess of 2500 K have found evidence for new physical processes at play in their atmospheres. In this work, we investigate the effects of the dissociation of molecular hydrogen and recombination of atomic hydrogen on the atmospheric circulation of ultra-hot ...

Reinflation of Warm and Hot Jupiters [PDF]
The Astrophysical Journal, 2020 Abstract Understanding the anomalous radii of many transiting hot gas-giant planets is a fundamental problem of planetary science. Recent detections of reinflated warm Jupiters orbiting post-main-sequence stars and the reinflation of hot Jupiters while their host stars evolve on the main sequence may help constrain models for the ...

The Frequency of Hot Jupiters in the Galaxy [PDF]
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.

Evaporation of hot jupiters and hot neptunes [PDF]
EPJ Web of Conferences, 2011 Among the nearly five hundred extra-solar planets known, almost 30% orbit closer than 0.1 AU from their parent star. We will review the observations and the corresponding models of the evaporation of these ‘hot jupiters’.

The evolution of hot Jupiters revealed by the age distribution of their host stars. [PDF]
Proc Natl Acad Sci U S A, 2023 Significance Hot Jupiters are the first exoplanet population discovered around main-sequence stars. However, their origin and evolution remain puzzled.

Hot Jupiters Are Asynchronous Rotators
The Astrophysical Journal LettersHot Jupiters are typically assumed to be synchronously rotating, from tidal locking. Their thermally driven atmospheric winds experience Lorentz drag on the planetary magnetic field anchored at depth.

TRANSITIONS IN THE CLOUD COMPOSITION OF HOT JUPITERS [PDF]
The Astrophysical Journal, 2016 ABSTRACT Over a large range of equilibrium temperatures, clouds shape the transmission spectrum of hot Jupiter atmospheres, yet their composition remains unknown. Recent observations show that the Kepler light curves of some hot Jupiters are asymmetric: for the hottest planets, the light curve peaks before secondary eclipse, whereas for ...

Superflares and “Hot-Jupiters” [PDF]
Symposium - International Astronomical Union, 2004 Schaefer, King & Deliyannis (2000) reported the discovery of powerful stellar flares on single, solar-type stars. The outbursts on these F8-G8 stars were 102–107 times more powerful than the largest solar flares. The observed properties are similar to the magnetic reconnection driven events of RS CVn binaries.

On a Possible Solution to the Tidal Realignment Problem for Hot Jupiters. [PDF]
Astrophys J, 2021 Hot stars with hot Jupiters have a wide range of obliquities, while cool stars with hot Jupiters tend to have low obliquities. An enticing explanation for this pattern is tidal realignment of the cool host stars, although this explanation assumes that ...
