Tidal Inflation is Stronger for Misaligned Neptune-sized Planets Than Aligned Ones
The Astrophysical JournalRecent observations have revealed an intriguing abundance of polar-orbiting Neptune-sized planets, many of which exhibit unusually inflated radii. While such misaligned orbits point to a complex dynamical history, the connection between their orbital ...

A Comprehensive Framework for Assessing Terrestrial Analogue Field Sites for Ocean Worlds
Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract Field studies at terrestrial analogue sites represent an important contribution to the science of ocean worlds. The value of the science and technology investigations conducted at field analogue sites depends on the relevance of the analogue environment to the target ocean world.

Different Planetary Eccentricity-period (PEP) Distributions of Small and Giant Planets
The Astronomical JournalWe used the database of 1040 short-period (1 ≤ P < 200 days) exoplanets radial-velocity orbits to study the planetary eccentricity-period (PEP) distribution.

Earth tides, earthquake occurrence and earth deformation
, 2010 An analysis of Earth deformation, earthquakes and tides has been undertakenusing Earth tide and interferometric SAR data from ESA satellites. The abilityof Earth tides to trigger earthquakes has been investigated by measuring thestatistical relationship ...

The Astronomical JournalBefore the launch of the Kepler Space Telescope, models of low-mass planet formation predicted that convergent type I migration would often produce systems of low-mass planets in low-order mean-motion resonances.

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.ABSTRACT In our search for life beyond the Solar System, certain planetary bodies may be more conducive to life than Earth. However, the observability of these “superhabitable” (SH) planets in the habitable zones around K dwarf stars has not been fully modeled. This study addresses this gap by modeling the atmospheres of SH exoplanets.

Initial Thermal States of Super‐Earth Exoplanets and Implications for Early Dynamos
Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.Abstract The accretion of Earth and the formation of a metallic core released a large amount of primordial heat and may have enabled its evolution into a habitable world. Metal‐silicate segregation likely occurs in super‐Earth exoplanets as well, but its influence on their initial thermal states has not been fully examined.

Empirical Constraints on Tidal Dissipation in Exoplanet Host Stars
The Astrophysical JournalThe orbits of short-period exoplanets are sculpted by tidal dissipation. However, the mechanisms and associated efficiencies of these tidal interactions are poorly constrained.
