Planetary Obliquity Excitation through Pre-main-sequence Stellar Evolution

The Astrophysical Journal
A planet’s axial tilt (“obliquity”) substantially affects its atmosphere and habitability. It is thus essential to comprehend the various mechanisms that can excite planetary obliquities, particularly at the primordial stage.

Spin Dynamics of Planets in Resonant Chains

The Astrophysical Journal
About a dozen exoplanetary systems have been discovered with three or more planets participating in a sequence of mean-motion resonances. The unique and complex architectures of these so-called “resonant chains” motivate efforts to characterize their ...

The PFS View of TOI-677 b: A Spin–Orbit Aligned Warm Jupiter in a Dynamically Hot System

The Astronomical Journal
TOI-677 b is part of an emerging class of “tidally detached” gas giants ( a / R _⋆ ≳ 11) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet formation, which must account for

Tidal Migration of Exoplanets around M Dwarfs: Frequency-dependent Tidal Dissipation

The Astrophysical Journal
The orbital architectures of short-period exoplanet systems are shaped by tidal dissipation in their host stars. For low-mass M dwarfs whose dynamical tidal response comprises a dense spectrum of inertial modes at low frequencies, resolving the frequency

Ocean Tides on Asynchronously Rotating Planets Orbiting Low-mass Stars

The Astrophysical Journal
Planets in the liquid-water habitable zone of low-mass stars experience large tidal forces, 10 ^3 –10 ^4 times those on Earth, due to the small distance between the habitable zone and the host stars.
