Angular Momentum Balance of Superrotation in Venus's Middle and Upper Atmosphere Simulated by AFES‐Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Based on simulations of the Venusian atmosphere using the AFES‐Venus GCM, we investigated the angular momentum (AM) balance that maintains the atmospheric superrotation (SR) at 35–90 km altitudes. In and above the cloud layer, the Eulerian‐mean meridional circulation consists of Hadley‐like cells at low latitudes and Ferrel‐like cells at ...

The OMEGA/Mars Express Dust Storm Catalog

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract This paper describes the OMEGA Dust Storm Catalogue (ODSC), built over almost 4 Martian Years (end of MY 26 to mid MY 30d) from OMEGA/Mars Express hyperspectral observations. A storm detection method has been developed based on a pixel clustering algorithm applied to the OMEGA dust optical depth retrievals made at 0.9 μ ${\upmu }$m.

The Impact of the Sulfur Allotropes and Sulfur Hydrides on the Venus Cloud Chemistry

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Venus is home to vivid sulfur chemistry, with SO2 ${\text{SO}}_{2}$ as the major sulfur gas species and a global cloud layer between 47 and 70 km composed of H2SO4 ${\mathrm{H}}_{2}{\text{SO}}_{4}$ and H2 ${\mathrm{H}}_{2}$O. The chemistry in the clouds has been extensively studied with 1D models, but none is able to reproduce the three orders

A cooled telescope for infrared balloon astronomy [PDF]

The characteristics of a 16 inch liquid helium cooled Cassegrain telescope with vibrating secondary mirror are discussed. The telescope is used in making far infrared astronomical observations. The system houses several different detectors for multicolor

Saponite Bearing Material Excavated During the Formation of a Recent 25‐m‐Diameter Impact Crater in Southeastern Arabia Terra on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Context Imager (CTX), and High Resolution Imaging Science Experiment observations were analyzed for a 25‐m‐wide impact crater and associated ejecta deposits located in the dust‐covered Arabia Terra region.

Modeling the Lunar Thermal Emission Phase Function With the Diviner Lunar Radiometer

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The lunar thermal emission phase function (EPF) describes the anisotropic variation in observed infrared emission and brightness temperature with illumination and viewing geometry. The EPF is caused by small‐scale surface roughness below the resolution of current orbital data sets.

Stellar bars and the spatial distribution of infrared luminosity [PDF]

Ground-based 10 micron observations of the central region of over 100 infrared luminous galaxies are presented. A first order estimate of the spatial distribution of infrared emission in galaxies is obtained through a combination of ground-based and ...

First Results from WINERED: Detection of Emission Lines from Neutral Iron and a Combined Set of Trace Species on the Dayside of WASP-189 b

The Astronomical Journal
Ground- and space-based observations have revealed that ultrahot Jupiters (UHJs, T _eq  > 2200 K) typically have inverted thermal profiles, while cooler hot Jupiters have noninverted ones.

Challenges in Simultaneous Microstructuring and Hyperdoping of Germanium with Ultrafast Laser

physica status solidi (a), Volume 223, Issue 8, 22 April 2026.
Femtosecond laser processing is explored as a single‐step route to microstructure and hyperdope germanium for extended infrared absorption. Comparative experiments with and without a Ti precursor reveal that Ge's shallow green light absorption and low thermal conductivity drive intense localized melting, evaporation, and redeposition. Post‐cleaning and
