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

The Atmospheric Circulation of Ultra-hot Jupiters [PDF]
The Astrophysical Journal, 2019 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.

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.

Hot Jupiters and Cool Stars [PDF]
The Astrophysical Journal, 2014 Close-in planets are in jeopardy as their host stars evolve off the main sequence to the subgiant and red giant phases. In this paper, we explore the influences of the stellar mass (in the range 1.5--2\Mso ), mass-loss prescription, planet mass (from ...

Reinflation of Warm and Hot Jupiters [PDF]
The Astrophysical Journal, 2020 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

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’.

Circulation and Dissipation on Hot Jupiters [PDF]
The Astrophysical Journal, 2010 Many global circulation models predict supersonic zonal winds and large vertical shears in the atmospheres of short-period jovian exoplanets. Using linear analysis and nonlinear local simulations, we investigate hydrodynamic dissipation mechanisms to ...

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.

Atmospheric Escape from Hot Jupiters [PDF]
Astronomy & Astrophysics, 2004 The extra-solar planet HD209458b has been found to have an extended atmosphere of escaping atomic hydrogen (Vidal-Madjar et al. 2003), suggesting that ``hot Jupiters'' closer to their parent stars could evaporate. Here we estimate the atmospheric escape (

Evolution of Ohmically Heated Hot Jupiters [PDF]
The 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 ...
