Mapping Exoplanets

, 2020
The varied surfaces and atmospheres of planets make them interesting places to live, explore, and study from afar. Unfortunately, the great distance to exoplanets makes it impossible to resolve their disk with current or near-term technology. It is still

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 ...

Effects of Planetary Parameters on Disequilibrium Chemistry in Irradiated Planetary Atmospheres: From Gas Giants to Sub-Neptunes

The Astrophysical Journal
A primary goal of characterizing exoplanet atmospheres is to constrain planetary bulk properties, such as their metallicity, C/O ratio, and intrinsic heat.

Radiative braking in the extended exosphere of GJ436b

, 2015
The recent detection of a giant exosphere surrounding the warm Neptune GJ436 b has shed new light on the evaporation of close-in planets, revealing that moderately irradiated, low-mass exoplanets could make exceptional targets for studying this mechanism

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 ...

Thermoelastic Contraction as a Suppressor of Atmospheric Escape in Close-in Exoplanets

The Astrophysical Journal
The survival of volatile-rich atmospheres on close-in exoplanets challenges classical escape models. We identify a fully classical, interior-driven correction: thermoelastic contraction of the planetary mantle slightly increases the gravitational binding

Boundary Layers of Circumplanetary Disks around Spinning Planets. I. Effects of Rossby Waves

The Astrophysical Journal, 2023
Gas giant planets are believed to accrete from their circumplanetary disks (CPDs). The CPDs usually involve accretion through the boundary layer (BL) in the vicinity of planets. Prior studies have concentrated on the BL of nonspinning planets.

The MgI line: a new probe of the atmospheres of evaporating exoplanets

, 2014
Transit observations of HD209458b in the UV revealed signatures of neutral magnesium escaping the planet's upper atmosphere. The absorption detected in the MgI line provides unprecedented information on the physical conditions at the altitude where the ...

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 ...
