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.

Magnetic and tidal interactions in spin evolution of exoplanets [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractThe axis-rotational evolution of exoplanets on close orbits strongly depends on their magnetic and tidal interactions with the parent stars. Impulsive perturbations from a star created by periodical activity may accumulate with time and lead to significant long-term perturbations of the planet spin evolution.

The Prevalence of Resonance Among Young, Close-in Planets
The Astronomical JournalMultiple planets undergoing disk migration may be captured into a chain of mean-motion resonances with the innermost planet parked near the disk’s inner edge.

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 ...

Interior Evolution of Magma Oceans Exoplanets
The magma ocean (MO) phase typically describes the early stage of rocky planets, during which the entire planet is molten due to heat generated by accretion processes. In the case of short-period exoplanets inside the runaway greenhouse limit, this phase may last Gyrs, until the inventory of major greenhouse gasses, such as H2O and H2, is exhausted ...

Investigating the Origins of Hot Neptunes from Radial Velocity Data
The Astronomical JournalHot 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.

EUV influences on exoplanet atmospheric stability and evolution
, 2019 The planetary effective surface temperature alone is insufficient to characterize exoplanet atmospheres and their stability or evolution. Considering the star-planet system as a whole is necessary, and a critical component of the system is the photoionizing stellar extreme ultraviolet emission (EUV; 100-912 ).

Three-dimensional Orbital Architectures and Detectability of Adjacent Companions to Hot Jupiters
The Astrophysical JournalThe orbital properties of the (as yet) small population of hot Jupiters with nearby planetary companions provide valuable constraints on the past migration processes of these systems.

Most Super-Earths Have Less Than 3% Water
The Astrophysical JournalSuper-Earths are highly irradiated, small planets with bulk densities approximately consistent with Earth. We construct combined interior atmosphere models of super-Earths that trace the partitioning of water throughout a planet, including an iron-rich ...
