DYNAMICAL MEASUREMENTS OF THE INTERIOR STRUCTURE OF EXOPLANETS [PDF]
The Astrophysical Journal, 2013 Giant gaseous planets often reside on orbits in sufficient proximity to their host stars for the planetary quadrupole gravitational field to become non-negligible. In presence of an additional planetary companion, a precise characterization of the system's orbital state can yield meaningful constraints on the transiting planet's interior structure ...

Tidal dynamics of transiting exoplanets [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractTransits give us the mass, radius, and orbital properties of the planet, all of which inform dynamical theories. Two properties of the hot Jupiters suggest they had a dramatic origin via tidal damping from high eccentricity. First, the tidally circularized planets (in the 1-4 day pile-up) lie along a relation or boundary in the mass-period ...

Atmospheres on Nonsynchronized Eccentric-tilted Exoplanets. I. Dynamical Regimes [PDF]
The Astrophysical Journal, 2019 Abstract Relatively long-period, nonsynchronized planets—such as warm Jupiters—potentially retain the primordial rotation, eccentricity, and obliquity that might encapsulate information on planetary climate and formation processes. To date, there has not been a systematic study on climate patterns on these planets that will significantly

TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
The Astronomical Journal, 2023 Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time could disrupt the delicate resonant configuration. We present TOI-1136, a 700 ±

TOI-1670 c, a 40 day Orbital Period Warm Jupiter in a Compact System, Is Well Aligned
The Astrophysical Journal Letters, 2023 We report the measurement of the sky-projected obliquity angle λ of the warm Jovian exoplanet TOI-1670 c via the Rossiter–McLaughlin effect. We observed the transit window during UT 2023 April 20 for 7 continuous hours with NEID on the 3.5 m WIYN ...

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems*
The Astronomical Journal, 2023 Abstract 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 experienced minimal dynamical disruptions, the spin–orbit orientations of these systems inform the typical outcomes of quiescent planet formation, as ...

The Diversity of Exoplanets: From Interior Dynamics to Surface Expressions [PDF]
Elements, 2021 The coupled interior–atmosphere system of terrestrial exoplanets remains poorly understood. Exoplanets show a wide variety of sizes, densities, surface temperatures, and interior structures, with important knock-on effects for this coupled system. Many exoplanets are predicted to have a “stagnant lid” at the surface, with a rigid stationary crust ...
