Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...

Exploring Warm Jupiter Migration Pathways with Eccentricities. I. Catalog of Uniform Keplerian Fits to Radial Velocities of 200 Warm Jupiters

The Astrophysical Journal Supplement Series
Giant planets are expected to predominantly form beyond the water-ice line and occasionally undergo inward migration. Unlike hot Jupiters, which can result from high-eccentricity tidal migration, warm Jupiters between 0.1 and 1 au (≈10–365 days) are in ...

Propagation Dynamics of Fast Electron Beam and Its Electron Cyclotron Maser Emission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Fast electron beams (FEBs) and coherent radio bursts both are very common plasma activity phenomena in the cosmos. The electron cyclotron maser (ECM) instability driven by FEBs trapped in magnetic fields can directly amplify radio wave radiations.

Stellar rotation and its connection to the evolution of hydrogen‐dominated atmospheres of exoplanets [PDF]

Astronomische Nachrichten, 2021
AbstractThe population of known low‐ to intermediate‐mass exoplanets shows a large spread in densities, which is believed to be due to the diversity of planetary atmospheres and thus controlled by planetary atmospheric mass loss. One of the main drivers of long‐term atmospheric escape is the absorption of high‐energy X‐ray + extreme ultraviolet (XUV ...

A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

Helium Depletion in Escaping Atmospheres of Sub-Neptunes: A Signature of Primary-to-secondary Transition

The Astrophysical Journal
Short-period sub-Neptunes are common in extrasolar systems. These sub-Neptunes are generally thought to have primary atmospheres of protoplanetary-disk gas origin.

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

Journal 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

Resonant Super-Earths Dancing with EKL Oscillations: Transit Timing Variation Phase Excitation and Resonance Disruption by EKL Interactions between a Cold Jupiter and Stellar Companion

The Astronomical Journal
Near-resonant Kepler planets are dynamically hot, as evidenced by nonzero transit timing variation (TTV) phases, indicating that free eccentricities are not damped. Recent observations suggest that circulating near-resonant planets tend to be dynamically
