Hot Jupiters Are Asynchronous Rotators [PDF]

The Astrophysical Journal Letters
Hot 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.

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.

Limited Hysteresis in the Atmospheric Dynamics of Hot Jupiters [PDF]

The Astrophysical Journal
Over the past two decades, a coherent picture has emerged of the atmospheric dynamics of hot Jupiters from a combination of three-dimensional general circulation models and astronomical observations.

Evidence for Primordial Alignment II: Insights from Stellar Obliquity Measurements for Hot Jupiters in Compact Multiplanet Systems [PDF]

The Astronomical Journal
A significant fraction of hot Jupiters have orbital axes misaligned with their host stars’ spin axes. The large stellar obliquities of these giants have long been considered potential signatures of high-eccentricity migration, which is expected to clear ...

Kepler constraints on planets near hot Jupiters. [PDF]

Proc Natl Acad Sci U S A, 2012
We present the results of a search for planetary companions orbiting near hot Jupiter planet candidates (Jupiter-size candidates with orbital periods near 3 d) identified in the Kepler data through its sixth quarter of science operations.

Patchy Nightside Clouds on Ultra-hot Jupiters: General Circulation Model Simulations with Radiatively Active Cloud Tracers [PDF]

, 2022
The atmospheres of ultra-hot Jupiters have been characterized in detail through recent phase curve and low- and high-resolution emission and transmission spectroscopic observations.

Colour–colour and colour–magnitude diagrams for hot Jupiters [PDF]

, 2020
We use ground-based and space-based eclipse measurements for the near-infrared (IR) bands (JHKs) and Spitzer 3.6- and 4.5-μm bands to construct colour–colour and colour–magnitude diagrams for hot Jupiters.

TESS giants transiting giants V - Two hot Jupiters orbiting red-giant hosts [PDF]

, 2023
: In this work we present the discovery and confirmation of two hot Jupiters orbiting red-giant stars, TOI-4377 b and TOI-4551 b, observed by TESS in the southern ecliptic hemisphere and later followed-up with radial-velocity (RV ...

Occurrence rate of hot Jupiters orbiting red giant stars [PDF]

, 2022
Context. Hot Jupiters form an enigmatic class of object whose formation pathways are not yet clear. Determining their occurrence rates as a function of orbit, planet and stellar mass, and system age can be an important ingredient for understanding how ...

The effect of interior heat flux on the atmospheric circulation of hot and ultra-hot Jupiters [PDF]

, 2022
Many hot and ultra-hot Jupiters have inflated radii, implying that their interiors retain significant entropy from formation. These hot interiors lead to an enhanced internal heat flux that impinges upon the atmosphere from below.
