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 ...

An Eccentric Sub-Neptune Moving Into the Evaporation Desert
The Astrophysical Journal LettersThough missions such as Kepler, K2, and TESS have discovered >2000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in ( P ≲ 3 days) orbits. This feature, called the Neptune desert or the evaporation desert, is believed to be

Hyades Member K2-136c: The Smallest Planet in an Open Cluster with a Precisely Measured Mass
The Astronomical Journal, 2023 K2-136 is a late-K dwarf (0.742 ± 0.039 M _⊙ ) in the Hyades open cluster with three known, transiting planets and an age of 650 ± 70 Myr. Analyzing K2 photometry, we found that planets K2-136b, c, and d have periods of 8.0, 17.3, and 25.6 days and radii

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.

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.

Spectrometric method for detecting exoplanets as another test to verify the invariance of the velocity of light [PDF]
Moscow University Physics Bulletin, 2011 Hypothetical influences of variability of light velocity due to the parameters of the source of radiation, for the results of spectral measurements of stars to search for exoplanets are considered. Accounting accelerations of stars relative to the barycenter of the star - a planet (the planets) was carried out.
