Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Intra‐Tessera Plains: Implications of Their Radar Properties for Surface Processes on Venus

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Intra‐tessera plains are radar‐dark plains deposits that occur within tesserae. Their emplacement mechanism(s) and composition are poorly constrained, though they are hypothesized to be basaltic lava flows. Here, we map intra‐tessera plains within 16 different tesserae spanning various latitudes and elevations.

The Role of Chlorate‐Driven Oxidative Weathering in Shaping Clay Deposits on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Oxidized clays and the widespread Al/Si‐over‐Fe/Mg stratigraphy on Mars imply prolonged water‐rock interactions and efficient oxidative weathering despite the largely anoxic conditions of Early Mars when most deposits formed during the climate optimum.

Ferric Chloride: The Venusian Unknown UV Absorber?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.
