Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Discovery of a Transiting Adolescent Sub-Neptune Exoplanet with K2 [PDF]

, 2018
The role of stellar age in the measured properties and occurrence rates of exoplanets is not well understood. This is in part due to a paucity of known young planets and the uncertainties in age-dating for most exoplanet host stars.

Investigating the Origins of Hot Neptunes from Radial Velocity Data

The Astronomical Journal
Hot Neptunes are extrasolar planets that are similar in size to Neptune in our solar system but are much closer to their host stars, completing an orbit in 10 days or less. The origin of hot Neptunes is not fully understood.

Neuromorphic Computing with Memcapacitors: Advancements, Challenges, and Future Directions

Advanced Electronic Materials, Volume 11, Issue 18, November 4, 2025.
Neuromorphic computing reduces energy costs by integrating memory and processing in event‐driven architectures, achieving energy usage as low as 10–30 pJ per operation for memcapacitor‐based synapses. Memcapacitors are reviewed as strong contenders for neuromorphic computing, enhancing AI acceleration through charge‐based computations, high resistance,

Orbital Migration Through Atmospheric Mass Loss

The Astronomical Journal
Atmospheric mass loss is thought to have strongly shaped the sample of close-in exoplanets. These atmospheres should be lost isotropically, leading to no net migration on the planetary orbit.

Direct Imaging of a Cold Jovian Exoplanet in Orbit around the Sun-like Star GJ 504 [PDF]

, 2013
Several exoplanets have recently been imaged at wide separations of >10 AU from their parent stars. These span a limited range of ages ( 0.5 mag), implying thick cloud covers.

The Orbit of Warm Jupiter WASP-106 b is Aligned with its Star

The Astronomical Journal, 2023
Understanding orbital obliquities, or the misalignment angles between a star’s rotation axis and the orbital axis of its planets, is crucial for unraveling the mechanisms of planetary formation and migration.

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

The Astrophysical Journal
Abstract 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 dependence of tidal dissipation is crucial to capturing the effect of tides
