Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

A Dynamic Scheme to Assess Habitability of Exoplanets
, 2012 In the next few years, the number of catalogued exoplanets will be counted in the thousands and with it the need will arise to prioritize them in regard to habitability and the potential presence of life. Here, we suggest a first attempt of a dynamic scheme for classification based on our current understanding of parameters that are consistent and ...

Characterisation of exoplanet atmospheres using high-resolution spectroscopy [PDF]
The characterisation of exoplanet atmospheres is crucial to understanding planet formation, the exploration of extreme atmospheric physics, finding habitable worlds, and searching for extraterrestrial life, but challenged by the overwhelming star-to ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.Abstract Low clouds (LC) are the largest source of uncertainty in the climate response to increased CO2 ${\text{CO}}_{2}$ in global climate models. This is due to the multitude of factors that affect their behavior and how these are characterized across models.

Dynamical Mass of the Exoplanet Host Star HR 8799
The Astronomical Journal, 2022 Abstract HR 8799 is a young A5/F0 star hosting four directly imaged giant planets at wide separations (∼16–78 au), which are undergoing orbital motion and have been continuously monitored with adaptive optics imaging since their discovery over a decade ago. We present a dynamical mass of HR 8799 using 130 epochs of relative astrometry of

High Resolution Transmission Spectroscopy as a Diagnostic for Jovian Exoplanet Atmospheres: Constraints from Theoretical Models [PDF]
, 2014 We present high resolution transmission spectra of giant planet atmospheres from a coupled 3-D atmospheric dynamics and transmission spectrum model that includes Doppler shifts which arise from winds and planetary motion. We model jovian planets covering

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.

Glass rain : modelling the formation, dynamics and radiative-transport of cloud particles in hot Jupiter exoplanet atmospheres [PDF]
, 2017 The atmospheres of exoplanets are being characterised in increasing detail by observational facilities and will be examined with even greater clarity with upcoming space based missions such as the James Webb Space Telescope (JWST) and the Wide Field ...

Effects of Hot Oxygen Corona on Ion Escape From Venus‐Like Planets
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract Due to the lack of a significant planetary magnetic field, the upper atmospheres of Venus‐like planets interact directly with the stellar wind. Therefore, thermal atomic oxygen in the thermosphere and hot oxygen in the corona produced by non‐thermal processes in the upper atmosphere act as a source of ion pickup loss.
