Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Venus as an exoplanet: effect of stellar, orbital, planetary and atmospheric properties upon composition, habitability and detectability

open access: yes, 2023
The newly selected Venus missions EnVISION and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) by ESA and NASA offer new opportunities for studying Venus but will also contribute to furthering our knowledge of Venus as an ...

Hot Spot Offset Variability from Magnetohydrodynamical Thermoresistive Instability in Hot Jupiters

open access: yesThe Astrophysical Journal
Hot Jupiter (HJ) atmospheres are possibly subject to a thermoresistive instability (TRI). Such an instability may develop as the ohmic heating increases the electrical conductivity in a positive feedback loop, which ultimately leads to a runaway of the ...

The Variable Detection of Atmospheric Escape around the Young, Hot Neptune AU Mic b

open access: yesThe Astronomical Journal, 2023
Photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized exoplanets can provide insight into and characterize which mechanisms drive this evolution and at what ...

Inferring Io's Internal Properties by Combining Gravity Measurements and Volcanic Activity

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract With its extreme geological activity, Io represents an archetype for tidally heated exoplanets/moons and provides insight into early stages of terrestrial planet evolution. Decades of ground‐based observations and multiple space missions have refined our understanding of Io, yet it remains debated where inside Io the tidal heating takes place.

The Impact of the Explicit Representation of Convection on the Climate of a Tidally Locked Planet in Global Stretched-mesh Simulations

open access: yesThe Astrophysical Journal
Convective processes are crucial in shaping exoplanetary atmospheres but are computationally expensive to simulate directly. A novel technique of simulating moist convection on tidally locked exoplanets is to use a global 3D model with a stretched mesh ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?

open access: yesGlobal Policy, Volume 17, Issue 4, Page 553-565, September 2026.
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Exoplanet Atmospheres [PDF]

open access: yes, 2010
At the dawn of the first discovery of exoplanets orbiting Sun-like stars in the mid-1990s, few believed that observations of exoplanet atmospheres would ever be possible.
