Time-scales of close-in exoplanet radio emission variability [PDF]

, 2015
We investigate the variability of exoplanetary radio emission using stellar magnetic maps and 3D field extrapolation techniques. We use a sample of hot Jupiter hosting stars, focusing on the HD 179949, HD 189733 and tau Boo systems.

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

The Inhomogeneity Effect. III. Weather Impacts on the Heat Flow of Hot Jupiters

The Astrophysical Journal, 2023
The interior flux of a giant planet impacts atmospheric motion, and the atmosphere dictates the interior’s cooling. Here we use a non-hydrostatic general circulation model (Simulating Non-hydrostatic Atmospheres on Planets) coupled with a multi-stream ...

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.

JWST-TST DREAMS: Nonuniform Dayside Emission for WASP-17b from MIRI/LRS

The Astronomical Journal
We present the first spectroscopic characterization of the dayside atmosphere of WASP-17b in the mid-infrared using a single JWST MIRI/LRS eclipse observation.

The Architectural Design Rules of Solar Systems based on the New Perspective

, 2009
On the basis of the Lunar Laser Ranging Data released by NASA on the Silver Jubilee Celebration of Man Landing on Moon on 21st July 1969-1994, theoretical formulation of Earth-Moon tidal interaction was carried out and Planetary Satellite Dynamics was ...

Community Voices on the Future of Radiation Belt Research: A Summary of the 2024 GEM Radiation Belt Focus Group Round‐Table Discussion

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies. Understanding the dynamics of the radiation belts is critical not only for advancing fundamental plasma physics but also for predicting and ...

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...

Peas-in-a-pod across the Radius Valley: Rocky Systems Are Less Uniform in Mass but More Uniform in Size and Spacing

The Astrophysical Journal Letters
The ubiquity of “peas-in-a-pod” architectural patterns and the existence of the radius valley each presents a striking population-level trend for planets with R _p ≤ 4 R _⊕ that serves to place powerful constraints on the formation and evolution of these
