Wide Binary Orbits Are Preferentially Aligned with the Orbits of Small Planets, but Probably Not Hot Jupiters

The Astronomical Journal
Studying 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

Hot Jupiters Are Asynchronous Rotators

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.

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

The 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.

Damping Obliquities of Hot Jupiter Hosts by Resonance Locking

The Astrophysical Journal Letters
When 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.

Shedding Light on Desert Dwellers

The Astrophysical Journal
The “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 Letters
The 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 ...
