Solar‐Asynchronous Tides and Stationary Planetary Waves in Mars Thermosphere Derived From MAVEN Data

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract Measurements of Ar and N2 ${\mathrm{N}}_{2}$ densities in Mars' thermosphere between 160 and 250 km altitude from the Mars Atmosphere and Volatile Evolution (MAVEN) Neutral Gas and Ion Mass Spectrometer (NGIMS) during February 2015–February 2023 are analyzed to derive solar‐asynchronous tides DE2, DE1, and SE1, and stationary planetary waves ...

Extended Scenarios for Solar Radio Emissions With Downshifted Electron Beam Plasma Excitations

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract First‐principle studies of radiative processes aimed at explaining the origin of type II and type III solar radio bursts raise questions on the implications of downshifted electron beam plasma excitations with frequency (slightly) below the plasma frequency ω≲ωpe $\left(\omega \lesssim {\omega }_{pe}\right)$ in the generation of radio ...
