The Astronomical JournalStudying the relative orientations of the orbits of exoplanets and wide-orbiting binary companions (semimajor axis greater than 100 au) can shed light on how planets form and evolve in binary systems. Previous observations by multiple groups discovered a

Planet–Planet Scattering Explains the Mass–Eccentricity Relation of Warm Jupiters
The Astrophysical Journal LettersWarm Jupiters—giant planets with orbital periods of ∼10–365 days—exhibit a positive correlation between mass and eccentricity. We interpret this trend as the outcome of planet–planet scattering, representing a transition from collision-dominated ...

The Astrophysical Journal LettersThe 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.

Damping Obliquities of Hot Jupiter Hosts by Resonance Locking
The Astrophysical Journal LettersWhen orbiting hotter stars, hot Jupiters are often highly inclined relative to their host star equator planes. By contrast, hot Jupiters orbiting cooler stars are more aligned.

The Discovery of Five Hot Jupiters by TESS
The Astronomical JournalDespite decades of research on hot Jupiters, there are still several theories for their formation. Perhaps hot Jupiters form in several ways. Atmospheric and dynamical studies have the capability to constrain the formation scenarios.

Shedding Light on Desert Dwellers
The Astrophysical JournalThe “sub-Jovian desert” (2 ≲ R _p ≲ 10 R _⊕ , periods ≲3 days) is sparsely populated but no longer empty. Recent surveys have revealed that planets residing in the desert are dense ( ρ ≳ 1 g cm ^−3 ), massive (∼10−50 M _⊕ ), and orbit metal-rich stars

A Larger Sample Confirms Small Planets around Hot Stars Are Misaligned
The Astrophysical Journal LettersThe distribution of stellar obliquities provides critical insight into the formation and evolution pathways of exoplanets. In the past decade, it was found that hot stars hosting hot Jupiters are more likely to have high obliquities than cool stars, but ...

General circulation modelling of close-in extrasolar giant planets [PDF]
, 2011 PhDA large fraction of the extrasolar planets detected so far are giant planets that have such short orbital periods (a few days) that they are thought to be tidally-synchronised with the host star. Such orbits lead to permanent day/night sides on the

Investigating the Origins of Hot Neptunes from Radial Velocity Data
The Astronomical JournalHot Neptunes are extrasolar planets that are similar in size to Neptune in our solar system but are much closer to their host stars, completing an orbit in 10 days or less. The origin of hot Neptunes is not fully understood.

Two-dimensional Models of Microphysical Clouds on Hot Jupiters. I. Cloud Properties
The Astrophysical JournalWe present a new two-dimensional, bin-scheme microphysical model of cloud formation in the atmospheres of hot Jupiters that includes the effects of longitudinal gas and cloud transport.
