Ocean Circulation on Tide-locked Lava Worlds: 3D Modeling with a Simple Boundary Iteration Method

The Astrophysical Journal Letters
Tide-locked lava worlds are surface-melted rocky planets under a 1:1 tidally locked orbit (i.e., synchronously rotating) with orbital period being equal to rotation period and with permanent hot dayside and cold nightside.

Resonant and Ultra-short-period Planet Systems Are at Opposite Ends of the Exoplanet Age Distribution

The Astronomical Journal
Exoplanet systems are thought to evolve on secular timescales over billions of years. This evolution is impossible to directly observe on human timescales in most individual systems.

Ground-breaking Exoplanet Science with the ANDES spectrograph at the ELT

, 2023
In the past decade the study of exoplanet atmospheres at high-spectral resolution, via transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular mapping, has become a powerful and consolidated methodology.

Coupled Planetary Interior and Tidal Evolution

The Astrophysical Journal
We present a new planetary structure/thermal evolution model, designed for use in problems that couple orbital dynamics with planetary structure. We first benchmark our structural/thermal evolution calculations against the MESA stellar evolution code ...

Architectures of Exoplanetary Systems. IV. A Multiplanet Model for Reproducing the Radius Valley and Intrasystem Size Similarity of Planets around Kepler’s FGK Dwarfs

The Astrophysical Journal
The Kepler-observed distribution of planet sizes has revealed two distinct patterns: (1) a radius valley separating super-Earths and sub-Neptunes and (2) a preference for intrasystem size similarity.

Terrestrial Exoplanet Internal Structure Constraints Enabled by Comprehensive Host Star Characterization Reveal That Terrestrial Planets in Mean Motion Resonances Are Water Rich

The Astrophysical Journal
Exoplanet mass and radius inferences fundamentally rely on host star mass and radius inferences. Despite the importance of host star mass, radius, and elemental abundance inferences for the derivation of exoplanet internal structure constraints ...

Hot Spot Offset Variability from Magnetohydrodynamical Thermoresistive Instability in Hot Jupiters

The Astrophysical Journal
Hot Jupiter (HJ) atmospheres are possibly subject to a thermoresistive instability (TRI). Such an instability may develop as the ohmic heating increases the electrical conductivity in a positive feedback loop, which ultimately leads to a runaway of the ...

Unexpected Near-Resonant and Metastable States of Young Multiplanet Systems

The Astrophysical Journal
Recent observations suggest that the incidence of near-resonant planets declines as planetary systems age, making young planetary systems key signposts of early dynamical evolution.

The GPI Exoplanet Survey II: Atmospheres and Orbits of Substellar Companions to Young and Nearby Stars

, 2017
The Gemini Planet Imager Exoplanet Survey (GPIES) is a 600-star survey for young Jovian-mass exoplanets at Solar System scales. To date, GPIES has imaged six exoplanets and four brown dwarfs and has developed the data reduction tools necessary to ...
