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.

Chemical modeling of exoplanet atmospheres
, 2014 International audienceThe past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored ...

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

Oxidation of the Interiors of Carbide Exoplanets
The Planetary Science Journal, 2020 Astrophysical measurements have shown that some stars have sufficiently high carbon-to-oxygen ratios such that the planets they host would be mainly composed of carbides instead of silicates.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer
Radio Science, Volume 61, Issue 6, June 2026.Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Soot Planets Instead of Water Worlds
The Astrophysical Journal LettersSome low-density exoplanets are thought to be water-rich worlds that formed beyond the snow line of their protoplanetary disk, possibly accreting coequal portions of rock and water.

Ohmic Dissipation During the Formation of Super-Earth
The Astrophysical Journal, 2023 The super-Earth population, as one of the representatives of exoplanets, plays an important role in constraining the planet formation theories. According to the prediction from core-accretion models, super-Earths should be rare because their masses are ...

Advancing Heliophysics and Space Weather Modeling Through Open Science
Space Weather, Volume 24, Issue 6, June 2026.Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

The thermal structure of exoplanet atmospheres [PDF]
, 2015 Context. The discovery of hot Jupiters, giant gas exoplanets on tight orbits close to their host star, has proven instrumental in the study of exoplanet atmospheres through transit spectroscopy.
