Evidence for Hidden Nearby Companions to Hot Jupiters
The first discovered extrasolar worlds—giant," hot Jupiter" planets on short-period orbits—
came as a surprise to solar system–centric models of planet formation, prompting the …

Orbital alignment of the eccentric warm Jupiter TOI-677 b
Warm Jupiters lay out an excellent laboratory for testing models of planet formation and
migration. Their separation from the host star makes tidal reprocessing of their orbits …

Soles. vii. the spin–orbit alignment of wasp-106 b, a warm jupiter along the kraft break
Although close-orbiting, massive exoplanets—known as hot and warm Jupiters—are among
the most observationally accessible known planets, their formation pathways are still not …

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems
The geometries of near-resonant planetary systems offer a relatively pristine window into the
initial conditions of exoplanet systems. Given that near-resonant systems have likely …

Hot Jupiters Have Giant Companions: Evidence for Coplanar High-eccentricity Migration
This study considers the characteristics of planetary systems with giant planets based on a
population-level analysis of the California Legacy Survey planet catalog. We identified three …

The spin–orbit misalignment of toi-1842b: The first measurement of the rossiter–mclaughlin effect for a warm sub-saturn around a massive star
The mechanisms responsible for generating spin–orbit misalignments in exoplanetary
systems are still not fully understood. It is unclear whether these misalignments are related …

The Orbital Architecture of Qatar-6: A Fully Aligned Three-body System?
The evolutionary history of an extrasolar system is, in part, fossilized through its planets'
orbital orientations relative to the host star's spin axis. However, spin–orbit constraints for …
