An Exoplanet in orbit around Tau^1 Gruis

, 2003
We report the detection of a new candidate exoplanet around the metal-rich star τ1 Gruis. With M sin i= 1.26 ± 0.18 MJup , a period of 1391 ± 300 d and an orbit with an eccentricity of 0.14 ± 0.14 it adds to the growing population of long-period ...

Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

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.

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,

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.

Survey and Modeling of Windblown Ejecta Deposits on Venus

AGU Advances, Volume 6, Issue 5, October 2025.
Abstract Venus' thick atmosphere rotates in the same direction as the solid body, but ∼60 times faster. This atmospheric superrotation has produced dozens of windblown ejecta deposits (“parabolas”) on the surface of Venus. The formation and modification of parabolas is an interplay between impacts, aeolian modification, and atmospheric dynamics.

Stellar companions to exoplanet host stars: A Lucky Imaging survey of transiting exoplanet systems

, 2016
About half of all nearby stars are part of a binary or multiple star system, yet little is known about how multiplicity affects the formation and subsequent evolution of planetary systems. For instance, stellar companions may promote the inward migration
