Evolution of Planetary Obliquity: The Eccentric Kozai–Lidov Mechanism Coupled with Tide
The Astrophysical Journal, 2023 Planetary obliquity plays a significant role in determining the physical properties of planetary surfaces and climate. As direct detection is constrained due to the present observation accuracy, kinetic theories are helpful for predicting the evolution ...

The Sensitivity of Eclipse Mapping to Planetary Rotation
The Astronomical Journal, 2022 Mapping exoplanets across phases and during secondary eclipse is a powerful technique for characterizing Hot Jupiters in emission. Since these planets are expected to rotate about axes normal to their orbital planes, with rotation periods synchronized ...

Kepler-80 Revisited: Assessing the Participation of a Newly Discovered Planet in the Resonant Chain
The Astronomical Journal, 2023 In this paper, we consider the chain of resonances in the Kepler-80 system and evaluate the impact that the additional member of the resonant chain discovered by Shallue & Vanderburg has on the dynamics of the system and the physical parameters that can ...

Dynamical Evolution of Closely Packed Multiple Planetary Systems Subject to Atmospheric Mass Loss
The Astronomical Journal, 2023 A gap in exoplanets’ radius distribution has been widely attributed to the photoevaporation threshold of their progenitors’ gaseous envelope. Giant impacts can also lead to substantial mass loss.

Tidal Dissipation Regimes among the Short-period Exoplanets
The Astrophysical Journal Letters, 2023 The efficiency of tidal dissipation provides a zeroth-order link to a planet’s physical properties. For super-Earth and sub-Neptune planets in the range R _⊕ ≲ R _p ≲ 4 R _⊕ , particularly efficient dissipation (i.e., low tidal quality factors) may ...
